[0045] An “effective amount” or a “therapeutically effective amount” of crystalline 5-MeO-DALT, 5-MeO-DALT fumarate, or crystalline 5-MeO-DALT fumarate according to the disclosure is generally in the range of about 0.1 to about 100 mg daily (oral dose), of about 0.1 to about 50 mg daily (oral dose) of about 0.25 to about 25 mg daily (oral dose), of about 0.1 to about 5 mg daily (oral dose) or of about 0.5 to about 2.5 mg daily (oral dose). The actual amount required for treatment of any particular patient may depend upon a variety of factors including, for example, the disease being treated and its severity; the specific pharmaceutical composition employed; the age, body weight, general health, sex, and diet of the patient; the mode of administration; the time of administration; the route of administration; and the rate of excretion; the duration of the treatment; any drugs used in combination or coincidental with the specific compound employed; and other such factors well known in the medical arts. These factors are discussed in Goodman and Gilman's “The Pharmacological Basis of Therapeutics,” Tenth Edition, A. Gilman, J. Hardman and L. Limbird, eds., McGraw-Hill Press, 155-173 (2001), which is incorporated herein by reference. Crystalline 5-MeO-DALT, 5-MeO-DALT fumarate, or crystalline 5-MeO-DALT fumarate according to the disclosure, compositions and pharmaceutical compositions containing them may be used in combination with other agents that are generally administered to a patient being treated for psychological and other disorders discussed above. They may also be co-formulated with one or more of such agents in a single pharmaceutical composition.

[0046] Depending on the type of composition or pharmaceutical composition, the excipient or pharmaceutically acceptable carrier may be chosen from any one or a combination of carriers known in the art. The choice of the pharmaceutically acceptable carrier depends upon the pharmaceutical form and the desired method of administration to be used. Preferred carriers include those that do not substantially alter crystalline 5-MeO-DALT, 5-MeO-DALT fumarate, or crystalline 5-MeO-DALT fumarate of the disclosure or produce undesirable biological effects or otherwise interact in a deleterious manner with any other component(s) of the pharmaceutical composition.

[0047] The compositions or pharmaceutical compositions of the disclosure may be prepared by methods known in the pharmaceutical formulation art, for example, see Remington's Pharmaceutical Sciences, 18th Ed., (Mack Publishing Company, Easton, Pa., 1990), which is incorporated herein by reference. In a solid dosage form, crystalline 5-MeO-DALT, 5-MeO-DALT fumarate, or crystalline 5-MeO-DALT fumarate of the disclosure may be admixed with at least one pharmaceutically acceptable excipient such as, for example, sodium citrate or dicalcium phosphate or (a) fillers or extenders, such as, for example, starches, lactose, sucrose, glucose, mannitol, and silicic acid, (b) binders, such as, for example, cellulose derivatives, starch, alignates, gelatin, polyvinylpyrrolidone, sucrose, and gum acacia, (c) humectants, such as, for example, glycerol, (d) disintegrating agents, such as, for example, agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, croscarmellose sodium, complex silicates, and sodium carbonate, (e) solution retarders, such as, for example, paraffin, (f) absorption accelerators, such as, for example, quaternary ammonium compounds, (g) wetting agents, such as, for example, cetyl alcohol, and glycerol monostearate, magnesium stearate and the like (h) adsorbents, such as, for example, kaolin and bentonite, and (i) lubricants, such as, for example, talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, or mixtures thereof. In the case of capsules, tablets, and pills, the dosage forms may also comprise buffering agents.

[0048] Excipients or pharmaceutically acceptable adjuvants known in the formulation art may also be used in the pharmaceutical compositions of the disclosure. These include, but are not limited to, preserving, wetting, suspending, sweetening, flavoring, perfuming, emulsifying, and dispensing agents. Prevention of the action of microorganisms may be ensured by inclusion of various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example, sugars, sodium chloride, and the like. If desired, a composition or a pharmaceutical composition of the disclosure may also contain minor amounts of auxiliary substances such as wetting or emulsifying agents, pH buffering agents, antioxidants, and the like, such as, for example, citric acid, sorbitan monolaurate, triethanolamine oleate, butylated hydroxytoluene, etc.

[0049] Solid dosage forms as described above may be prepared with coatings and shells, such as enteric coatings and others well known in the art. They may contain pacifying agents and can also be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Non-limiting examples of embedded compositions that may be used are polymeric substances and waxes. The active compounds may also be in microencapsulated form, if appropriate, with one or more of the above-mentioned excipients.

[0050] Suspensions, in addition to the active compounds, may contain suspending agents, such as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, or mixtures of these substances, and the like.

[0051] Solid dosage forms for oral administration, which includes capsules, tablets, pills, powders, and granules, may be used. In such solid dosage forms, the active compound may be mixed with at least one inert, pharmaceutically acceptable excipient (also known as a pharmaceutically acceptable carrier).

[0052] Administration of crystalline 5-MeO-DALT, 5-MeO-DALT fumarate, or crystalline 5-MeO-DALT fumarate of the disclosure in pure form, with a permeation enhancer, with stabilizers (e.g. antioxidants), or in an appropriate pharmaceutical composition may be carried out via any of the accepted modes of administration or agents for serving similar utilities. Thus, administration may be, for example, orally, buccally, nasally, parenterally (intravenous, intramuscular, or subcutaneous), topically, transdermally, intravaginally, intravesically, or intrasystemically, in the form of solid, semi-solid, lyophilized powder, liquid dosage forms, such as, for example, tablets, suppositories, pills, soft elastic and hard gelatin capsules, powders, suspensions, or aerosols, or the like, such as, for example, in unit dosage forms suitable for simple administration of precise dosages. One route of administration may be oral administration, using a convenient daily dosage regimen that can be adjusted according to the degree of severity of the disease-state to be treated.

[0056] 5-methoxy-N,N-diallyltryptamine has a single tryptamine molecule in the asymmetric unit. The asymmetric unit of 5-methoxy-N,N-diallyltryptamine contains a single tryptamine molecule shown in FIG. 1. The indole unit is near planar with a deviation from planarity of 0.015 Å. The methoxy group is in the same plane, with the indole and methoxy group showing an r.m.s. deviation of only 0.025 Å. The ethylamine group is turned significantly from the indole plane, with a C1-C8-C9-C10 torsion angle of 103.7 (2°). The molecules are held together by an N1-H1 . . . N2 hydrogen bond between the indole N—H and the amino nitrogen. These hydrogen bonds join the molecules together along [010]. The crystal packing of 5-methoxy-N,N-diallyltryptamine, viewed along the α-axis is shown in FIG. 2. The N—H . . . N hydrogen bonds are shown as dashed lines.

[0057] FIG. 3 is a simulated x-ray powder diffraction (XRPD) of crystalline 5-MeO-DALT from its single crystal data. Crystalline 5-MeO-DALT may be characterized by the XRPD peaks at 9.1, 11.4, and 21.4°2θ±0.2°2θ as well as by an XRPD pattern substantially similar to FIG. 3.

Example 2: Synthesis and Crystallization of 5-MeO-DALT Fumarate

[0058] 5-MeO-DALT fumarate was synthesized when 0.110 g of 5-MeO-DALT freebase was dissolved in 10 mL of methanol, and 47 mg of fumaric acid was added and refluxed overnight. 129 mg (82% yield) of white power was obtained upon removal of solvent in vacuo.

[0063] The asymmetric unit of 5-MeO-DALT fumarate contains one tryptammonium cation and one half of a fumarate dianion in the asymmetric unit. The tryptammonium and fumarate ions are held together in one-dimensional chains by a series of N—H . . . O hydrogen bonds. These chains are combinations of R.sup.4.sub.4(22) rings, and C.sup.2.sub.2(14) and C.sup.4.sub.4(28) parallel chains along [111]. The cation possesses a near planar indole ring, with a mean deviation from planarity of 0.011 Å. The methoxy group is turned slightly away from this plane, with a C2-C3-O1-C17 torsion angle of 13.9 (3°). The ethyl-amino group is turned away from this plane, with a C7-C8-C9-C10 torsion angle of 103.9 (2°). The second half of the fumarate dianion is generated by inversion, and the dianion is near planar, with a mean deviation from planarity of 0.057 Å. The carboxylate unit is delocalized, with C—O distances of 1.271 (2) and 1.240 (2) Å.

[0064] The two to one ratio as a dimer of 5-MeO-DALT fumarate is shown in FIG. 5.

[0065] The crystal packing of 5-MeO-DALT fumarate, viewed along the b axis, is shown in FIG. 6. The N—H . . . O hydrogen bonds are shown as dashed lines.

[0066] The tryptammonium cation and the fumarate dianion are linked together in the asymmetric unit through an N—H . . . O hydrogen bond between the ammonium nitrogen and a carboxylate oxygen. The indole nitrogen also exhibits an N—H . . . O hydrogen bond with another symmetry generated fumarate dianion. Two tryptammonium cations and two fumarate dianions are joined together through the N—H . . . O hydrogen bonds to form rings with graph-set notation R.sup.4.sub.4(22) (Etter et al., 1990). The rings are joined together by two parallel chains along [111]. These chains have graph-set notation C.sup.2.sub.2(14) and C.sup.4.sub.4(28). The chains and rings of crystalline 5-MeO-DALT fumarate are shown in FIG. 7.

[0067] The hydrogen bonding network along [111], which consists of R.sup.4.sub.4(22) rings that are joined together by two parallel C.sup.2.sub.2(14) and C.sup.4.sub.4(28) chains. The three components described in graph-set notation and the combined chain are shown in FIG. 7. Hydrogen bonds are shown as dashed lines.

[0068] FIG. 8 is a simulated x-ray powder diffraction (XRPD) of crystalline 5-MeO-DALT fumarate from its single crystal data. Crystalline 5-MeO-DALT fumarate may be characterized by the XRPD peaks at 7.2, 10.2, and 22.7°2θ±0.2°2θ as well as by an XRPD pattern substantially similar to FIG. 8.
