Reaction Steps

330 mg of N-[(1S,2R)-1-(3,5-difluorobenzyl)-2-hydroxy-3-({1-[3-(trifluoromethyl)phenyl]cyclopropyl}amino)propyl]-7-[methyl(methylsulfonyl)amino]-1-oxo-2-(1-propylbutyl)-1,2,3,4-tetrahydroisoquinoline-5-carboxamide are dissolved in 10 cm3 of ethyl ether at a temperature close to 20° C. 1 cm3 of a 2M solution of hydrochloric acid in ethyl ether is added, while stirring under argon, at a temperature of 20° C. The reaction mixture precipitates. The solid is filtered, washed with 5 cm3 of ethyl ether and dried under vacuum at a temperature of 35° C. for 3 h. 310 mg of N-[(1S,2R)-1-(3,5-difluorobenzyl)-2-hydroxy-3-({1-[3-(trifluoromethyl)phenyl]cyclopropyl}amino)propyl]-7-[methyl(methylsulfonyl)amino]-1-oxo-2-(1-propylbutyl)-1,2,3,4-tetrahydroisoquinoline-5-carboxamide hydrochloride (1:1) are obtained in the form of a white powder.
