실험 절차

WSC.HCl (95.9 mg, 0.5 mmol) was added to a solution of 2-acetoxy-5-chlorobenzoic acid (59.1 mg, 0.28 mmol), 2-amino-N-[3,5-bis(trifluoromethyl)phenyl]acetamide hydrochloride (80.8 mg, 0.25 mmol) and 1-hydroxybenzotriazole (37.2 mg, 0.28 mmol) in N,N-dimethylformamide (3 mL), and the mixture was stirred at room temperature for 3 hours. The reaction mixture was poured into diluted hydrochloric acid and extracted with ethyl acetate. After the ethyl acetate layer was washed with brine, dried over anhydrous sodium sulfate, the residue obtained by evaporation of the solvent under reduced pressure was purified by column chromatography on silica gel (n-hexane:ethyl acetate=3:2→1:1) to give the title compound (83.7 mg, 69.3%) as a white crystal.
