実験手順

To a solution of 980 mg (1 eq, 2.84 mmol) of (2E)-3-[4-{[(tert-butoxycarbonyl)amino]methyl}-3-(trifluoromethyl)phenyl]acrylic acid in 10 ml of dichloromethane were added 481 mg (1 eq, 2.84 mmol) of 6-chlorohydroxybenzotriazole and 707 mg (1.3 eq, 3.70 mmol) of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) and 733 mg (2 eq, 5.68 mmol, 989 μl) of Huenig's base. The reaction mixture was stirred at room temperature for 20 min. Then 1.04 g (1.5 eq, 4.26 mmol) of 2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethanamine as a solution in 1 ml of CH2Cl2 were added, and the mixture was stirred at room temperature for 16 h. The reaction mixture was concentrated under reduced pressure and partitioned between saturated Na2CO3 solution and ethyl acetate. After drying and concentrating the solvent, 2.108 g of tert-butyl {4-[(1E)-3-oxo-3-({2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethyl}amino)prop-1-en-1-yl]-2-(trifluoromethyl)benzyl}carbamate were obtained as an oil, which was converted in the next step without further purification.
