실험 절차

To a solution of (1S,2S)-1-N-[5-(trifluoromethyl)pyrazin-2-yl]cyclopentane-1,2-diamine hydrochloride (Intermediate 14; 60 mg, 0.21 mmol) in DMF (3 ml) was added 2-(trifluoromethyl)benzoic acid (CAS number 433-97-6; 60 mg, 0.21 mmol), TBTU (0.082 g, 0.25 mmol) and DIPEA (0.1 g, 0.84 mmol) and the reaction was stirred at room temperature for 2 hours. The reaction was diluted with water (25 ml) and extracted with ethyl acetate (30 ml×3). The organics were washed with water (50 ml), brine (25 ml), dried over sodium sulfate and concentrated in vacuo. The resulting residue was purified by column chromatography (silica, 0-45% ethyl acetate/n-hexane) to afford the title compound.
