Participants

Reaction Steps

326 mg of (2R,3S)-3-amino-4-(3,5-difluorophenyl)-1-({1-[3-(trifluoromethyl)phenyl]cyclopropyl}amino)butan-2-ol hydrochloride (2:1), 180 mg of 1-oxo-2-pentyl-1,2,3,4-tetrahydroisoquinoline-5-carboxylic acid, 14 mg of hydroxybenzotriazole, 165 mg of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 0.47 cm3 of N,N-diisopropylethylamine in 18 cm3 of dichloromethane are stirred for 20 h at a temperature close to 20° C. 10 cm3 of water and dichloromethane are added to the reaction medium. The suspension is filtered, washed successively with water and dichloromethane. The solid obtained is taken up in ethyl ether, filtered, washed with ethyl ether and dried under vacuum at 20° C. 360 mg of N-[(1S,2R)-1-(3,5-difluorobenzyl)-2-hydroxy-3-({1-[3-(trifluoromethyl)phenyl]cyclopropyl}amino)propyl]-1-oxo-2-pentyl-1,2,3,4-tetrahydroisoquinoline-5-carboxamide are obtained in the form of a white solid.
