To a solution of 4-(4-methyl-piperazin-1-ylmethyl)-3-trifluoromethyl-benzoic acid ethyl ester 37 (21 mg, 0.064 mmol) in ethanol (5 mL) was added 2N NaOH (0.318 mL, 0.636 mmol). The resulting mixture was stirred at rt for 2 h. The reaction mixture was acidified with 2N HCl solution and concentrated in vacuo to give the crude 4-(4-methyl-piperazin-1-ylmethyl)-3-trifluoromethyl-benzoic acid 38 (20 mg, 104%) which was used without further purification.
