PROCEDURE

实验过程

To 10 g (19.4 mmol) of ethyl 1-[(R)-2-tert-butoxycarbonylamino-3-(4-methoxyphenyl)-propionyl]-4-cyclohexylpiperidine-4-carboxylate (cf. preparation 19-1) in 80 mL of dichloromethane are added, at room temperature, 20 mL of trifluoroacetic acid. The reaction medium is stirred for 2 hours and the solvents are then evaporated off. Diethyl ether and a few drops of dichloromethane are added to the oil obtained, and the white solid obtained is filtered off and then dried. 8 g of ethyl 1-[(R)-2-amino-3-(4-methoxyphenyl)propionyl]-4-cyclohexylpiperidine-4-carboxylate trifluoroacetate are obtained in a yield of 78%.
