(73) For clarity purposes, reference is also made to the following statements below in the definitions of substitutions on alkyl etc. or aryl etc. that “wherein when different radicals R.sub.1 to R.sub.14″″ and R.sub.x, R.sub.x′, are present simultaneously in Formula I they may be identical or different”. This statement is reflected in the below general Formula (I.sup.7′) being derived from and falling into general Formula (I).

wherein R.sub.1, R.sub.2, R.sub.3, R.sub.3′, R.sub.4, R.sub.4′, R.sub.5, R.sub.5′, X, Y and p are as defined in the description. In addition, m′ (being 0 or 1), R.sub.5″ and R.sub.5′″ are added. As said above, this statement is thus reflected in that R.sub.5″ and R.sub.5″′ are or could be different from R.sub.5 and R.sub.5′ or not and—accordingly—m′ being 0 or 1 is naturally resulting from m (in general Formulas (I) to (I.sup.6′) being 1 or 2).

(75) The same would be applicable mutatis mutandis for general Formulas like general Formula (I) as well as the other general Formulas (I′) to (I.sup.6′) above, as well as to all the intermediates of synthesis.

(76) For clarity purposes, all groups and definitions described in the description and referring to compounds of general Formula (I), also apply to compounds of general Formula (I′), (I.sup.a′), (I.sup.b′), (I.sup.c′), (I.sup.2′), (I.sup.3′), (I.sup.4′), (I.sup.5′), or (I.sup.6′) or (I.sup.7′), as well as to all the intermediates of synthesis, when those groups are present in the mentioned general Markush formulae, since compounds of general Formula (I′), (I.sup.a′), (I.sup.b′), (I.sup.c′), (I.sup.2′), (I.sup.3′), (I.sup.4′), (I.sup.5′), (I.sup.6′) or (I.sup.7′) are included in the general Formula (I).

(77) For clarity purposes, the general Markush Formula (I)

(78) ##STR00017##
is equivalent to

(79) ##STR00018##
wherein only —C(R.sub.4R.sub.4′)—, —C(R.sub.5R.sub.5′)— and —C(R.sub.6R.sub.6′)— are included into the brackets and p, m and n mean the number of times that —C(R.sub.4R.sub.4′)—, —C(R.sub.5R.sub.5′)— and —C(R.sub.6R.sub.6′)— are repeated, respectively. The same would apply to general Markush Formulae (I′), (I.sup.a′), (I.sup.b′), (I.sup.c′), (I.sup.2′), (I.sup.3′), (I.sup.4′), (I.sup.5′) or (I.sup.6′) as well as to all the intermediates of synthesis.

(80) Thus, general Formula (I′) could also be expressed as general Formula (IZ′) etc.:

(81) ##STR00019##

(82) In addition, and for clarity purposes, it should further be understood that naturally if p, m or n are 0, then R.sub.1, X or R.sub.2 are still present in general Markush Formulae (I′), (I.sup.a′), (I.sup.b′), (I.sup.c′), (I.sup.2′), (I.sup.3′), (I.sup.4′), (I.sup.5′) or (I.sup.6′) as well as in all the intermediates of synthesis.

The term “solvate” according to this invention is to be understood as meaning any form of the active compound according to the invention in which this compound has attached to it via non-covalent binding another molecule (most likely a polar solvent). Especially preferred examples include hydrates and alcoholates, like methanolates or ethanolates.

(119) Any compound that is a prodrug of a compound according to the invention like a compound according to general formula I defined above is understood to be also covered by the scope of the invention. The term “prodrug” is used in its broadest sense and encompasses those derivatives that are converted in vivo to the compounds of the invention. Such derivatives would readily occur to those skilled in the art, and include, depending on the functional groups present in the molecule and without limitation, the following derivatives of the present compounds: esters, amino acid esters, phosphate esters, metal salts sulfonate esters, carbamates, and amides. Examples of well known methods of producing a prodrug of a given acting compound are known to those skilled in the art and can be found e.g. in Krogsgaard-Larsen et al. “Textbook of Drug design and Discovery” Taylor & Francis (April 2002).

(922) Scheme 1:

(923) A 4-step process is described for the preparation of compounds of general formula (I) starting from a ketone of formula II, as shown in the following scheme:

(924) ##STR00186##
wherein R.sub.1, R.sub.2, R.sub.3, R.sub.3′, R.sub.4, R.sub.4′, R.sub.5, R.sub.5′, R.sub.6, R.sub.6′, X, Y, m, n and p have the meanings as defined above for a compound of formula (I), LG represents a leaving group such such as halogen, mesylate, tosylate or triflate, with the proviso that when Y=CO it can only be chloro or bromo, V represents an aldehyde or another leaving group (such as halogen, mesylate, tosylate or triflate), P represents a suitable protecting group (preferably Boc) and P′ represents an orthogonal protecting group (preferably 4-methoxybenzyl or benzyl).

(925) The 4 step-process is carried out as described below:

(927) Step 2: A compound of formula Va is prepared by reacting a compound of formula III with an amine of formula IVa, in a suitable solvent such as an alcohol, preferably ethanol-water mixtures, at a suitable temperature comprised between room temperature and the reflux temperature.

(928) Step 3: A compound of formula VIIa is prepared by reacting a compound of formula Va with a compound of formula VI. Depending on the meaning of Y, the compound of formula VI can be of different nature and different reaction conditions will apply: a) When Y represents CO, VI is an acylating agent. The acylation reaction is carried out in a suitable solvent, such as dichloromethane or ethyl acetate-water mixtures; in the presence of an organic base such as triethylamine or diisopropylethylamine or an inorganic base such as K.sub.2CO.sub.3; and at a suitable temperature, preferably comprised between −78° C. and room temperature. b) When Y represents CH.sub.2, VI is an alkylating agent.

A second alkylation can be performed under the same reaction conditions to prepare a compound of formula Ig. An analogous double-alkylation process can be used for the preparation of compounds of formula Ia, by reacting a compound of formula Ie with an alkylating agent of formula XXVIIc, as an alternative to the procedure described in Scheme 2 for the preparation of compounds of formula Ia.

To a solution of intermediate 7A (156 mg, 0.48 mmol) in MeOH (2 mL), HCl (2M solution in diethyl ether, 2.4 mL, 4.8 mmol) was added, and the mixture was stirred at r.t. for 4 h. The solvent was evaporated under vacuum to give the corresponding di-HCl salt (143 mg, quantitative yield).

Title compound: A solution of the crude product obtained in step 1 (0.125 g, 0.42 mmol), DIPEA (0.366 mL, 2.1 mmol) and 3-fluoro-2-vinylpyridine hydrochloride (0.115 g, 0.72 mmol) in EtOH (1.2 mL) was heated at 90° C. in a sealed tube for 1 day. Additional 3-fluoro-2-vinylpyridine hydrochloride (0.034 g, 0.210 mmol) was added and the mixture heated at 90° C. for another day. The reaction mixture was allowed to cool to r.t. and the solvent was evaporated. It was diluted with DCM and washed twice with 1N NaOH.

(1101) To investigate binding properties of test compounds to human σ.sub.1 receptor, transfected HEK-293 membranes and [.sup.3H](+) -pentazocine (Perkin Elmer, NET-1056), as the radioligand, were used. The assay was carried out with 7 μg of membrane suspension, 5 nM of [.sup.3H](+)-pentazocine in either absence or presence of either buffer or 10 μM Haloperidol for total and non-specific binding, respectively. Binding buffer contained Tris-HCl 50 mM at pH 8. Plates were incubated at 37° C. for 120 minutes. After the incubation period, the reaction mix was then transferred to Multiscreen HTS, FC plates (Millipore), filtered and plates were washed 3 times with ice-cold 10 mM Tris-HCL (pH 7.4). Filters were dried and counted at approximately 40% efficiency in a MicroBeta scintillation counter (Perkin-Elmer) using EcoScint liquid scintillation cocktail

(1103) As this invention is aimed at providing a compound or a chemically related series of compounds which act as ligands of the σ.sub.1 receptor it is a very preferred embodiment in which the compounds are selected which act as ligands of the σ.sub.1 receptor and especially compounds which have a binding expressed as K.sub.i which is preferably <1000 nM, more preferably <500 nM, even more preferably <100 nM.

(1104) The following scale as been adopted for representing the binding to the σ.sub.1 receptor expressed as K.sub.i: + K.sub.i−σ.sub.1>=500 nM ++ K.sub.i−σ.sub.1<500 nM +++ K.sub.i−σ.sub.1<100 nM
All compounds prepared in the present application exhibit binding to the σ.sub.1 receptor, in particular the following binding results are shown:
