To a solution of (1S,2S)-1-N-[5-(trifluoromethyl)pyridin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 1; 50 mg, 0.20 mmol) in DMF (3 ml) was added 5-chloro-2-(2H-1,2,3-triazol-2-yl)benzoic acid (Intermediate 38a; CAS number 1293284-54-4; 45 mg, 0.204 mmol), TBTU (78 mg, 0.245 mmol) and DIPEA (40 mg, 0.306 mmol). The reaction was stirred at room temperature for 2 hours and was then diluted with water (25 ml) and extracted with ethyl acetate (3×30 ml). The organics were washed with water (25 ml), brine (20 ml), dried over sodium sulfate and concentrated in vacuo. The residue was then purified by column chromatography (silica, 0-45% ethyl acetate/n-hexane) to afford the title compound.
