실험 절차

4-(Cyclopropylmethoxy)benzoic acid (1.52 g, 7.90 mmol) prepared in Example 18 (18a) was added to a DMF (53 mL) solution of 2-({(2S)-2-amino-3-[4-(trifluoromethoxy)phenyl]propanoyl}amino)ethyl acetate (2.64 g, 7.90 mmol). To the mixture was added diethyl cyanophosphate (1.54 mL, 9.78 mmol) under ice-cooling with stirring, and then triethylamine (1.32 mL, 9.78 mmol) was dropwise added thereto over 5 minutes. The resulting mixture was stirred at room temperature for 2.5 hours, and to this reaction solution was added ethyl acetate (380 mL). The resulting mixture was washed with water (380 mL, three times) and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated, and the obtained residue was washed with ethyl acetate and dried to give 1.47 g of the title compound. The ethyl acetate used for the washing was also concentrated, and the resulting residue was washed with methanol to give 0.82 g of the title compound. These compound fractions were combined to give 2.29 g of the title compound (white powder, yield: 57%).
