1.5 g (1.84 mmol) of 2-{4-(2-({(2-(4-chlorophenyl)-1,3-thiazol-4-yl)methyl}sulfanyl)-3,5-dicyano-6-(pyrrolidin-1-yl)pyridin-4-yl)phenoxy}ethyl N-(tert-butoxycarbonyl)-L-alanyl-L-alaninate (Example 7A) were initially charged in 24 ml of dichloromethane. 18.37 ml of a 1N solution of hydrogen chloride in diethyl ether were added, and the reaction solution was then stirred at RT overnight. The solid formed was filtered off and washed with diethyl ether. This gave 1.44 g (97% of theory, purity about 94%) of the target compound.
