[0153] The compound represented by Formula 1 of the present invention can be used in the form of a pharmaceutically acceptable salt, and an acid addition salt formed by a pharmaceutically acceptable free acid is useful as the salt. The acid addition salt is obtained from inorganic acids (e.g., hydrochloric acid, nitric acid, phosphoric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, nitrous acid, phosphorous acid, etc.); non-toxic organic acids (e.g., aliphatic mono- and di-carboxylates, phenyl-substituted alkanoates, hydroxy alkanoates and alkanedioates, aromatic acids, aliphatic and aromatic sulfonic acids, etc.; organic acids (e.g., trifluoroacetic acid, acetate, benzoic acid, citric acid, lactic acid, maleic acid, gluconic acid, methanesulfonic acid, 4-toluenesulfonic acid, tartaric acid, fumaric acid, etc.). These types of pharmaceutically non-toxic salts include sulfate, pyrosulfate, bisulfate, sulfite, bisulfite, nitrate, phosphate, monohydrogen phosphate, dihydrogen phosphate, metaphosphate, pyrophosphate chloride, bromide, iodide, fluoride, acetate, propionate, decanoate, caprylate, acrylate, formate, isobutyrate, caprate, heptanoate, propiolate, oxalate, malonate, succinate, suberate, sebacate, fumarate, maleate, butyne-1,4-dioate, hexane-1,6-dioate, benzoate, chlorobenzoate, methylbenzoate, dinitrobenzoate, hydroxybenzoate, methoxybenzoate, phthalate, terephthalate, benzenesulfonate, toluenesulfonate, chlorobenzenesulfonate, xylenesulfonate, phenylacetate, phenylpropionate, phenylbutyrate, citrate, lactate, β-hydroxybutyrate, glycolate, maleate, tartrate, methanesulfonate, propanesulfonate, naphthalen-1-sulfonate, naphthalen-2-sulfonate, mandelate, etc.

[0155] In addition, a pharmaceutically acceptable metal salt may be prepared using a base. An alkali metal or alkaline earth metal salt is obtained, for example, by dissolving a compound in an excess alkali metal hydroxide or alkaline earth metal hydroxide solution, filtering the undissolved compound salt, and evaporating and drying the filtrate. In this case, it is pharmaceutically suitable to prepare a sodium, potassium, or calcium salt as the metal salt. In addition, the corresponding salt is obtained by reacting an alkali metal or alkaline earth metal salt with a suitable negative salt (e.g., silver nitrate).

<Experimental Example 1> Evaluation of Triple Reuptake Inhibitory Effect

[0280] In order to evaluate the reuptake inhibitory effect of the compounds of Examples according to the present invention on serotonin, norepinephrine and dopamine, the following experiments were performed, and the results are shown in Table 13.

[0281] To evaluate the reuptake inhibitory effect on dopamine, the dopamine transporter cDNA was transfected using the HEK-293 cell line, and then sub-seeded in a 24 well plate the next day. After removing the medium, each compound of Examples or Comparative Examples diluted to 1 μM in uptake buffer was added to a concentration of 200 μL/well and cultured at 37° C. for 15 minutes. 100 μL of uptake buffer containing 20-30 nM [3H]-DA was added and cultured at 37° C. for 5 minutes. The reaction solution was quickly removed and washed three times with 1 mL ice-cold uptake buffer. After dissolving the resultant in 1% SDS (0.5 mL), the degree of binding of radioisotope-labeled dopamine to the transporter was measured.

[0282] For norepinephrine(NE) and serotonin(5-HT), the degree of binding of radioisotope-labeled norepinephrine or serotonin to the transporter was measured in the same manner as above, except that cells transfected with NE or 5-HT transporter cDNA were used and [3H]-NE or [3H]-5-HT was used as a substrate.

[0283] In addition, when evaluating the reuptake inhibitory effect on dopamine, norepinephrine, and serotonin, the same method was performed without treating each compound of Examples or Comparative Examples as a control, the degree of binding of radioisotope-labeled dopamine, norepinephrine, and serotonin to the transporter was measured, and by using this as a reference (100%), the triple reuptake inhibitory effect was evaluated as a relative ratio (Ratio %). That is, in the control group, the binding of dopamine, norepinephrine, and serotonin to transporters is not inhibited, but when each compound of Examples is treated and thus the binding is inhibited, the Ratio % value decreases.

[0284] Meanwhile, the Ratio % values were compared, and in the case of compounds of Examples 1, 2, 10, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, and 31 with excellent reuptake inhibitory effects on dopamine, norepinephrine and serotonin, the concentration at which the Ratio % is 50% was calculated using a total of 6 concentrations (1 nM, 5 nM, 10 nM, 50 nM, 100 nM, and 1 μM) and expressed as IC.sub.50.
