Reaction Steps

420 mg (0.444 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-{(2S)-2,4-bis((tert-butoxycarbonyl)-amino)butanoyl}-L-alaninate were dissolved in 5 ml dichloromethane, and 4.442 ml of a 1N solution of hydrogen chloride in diethyl ether were added. After 4 hours of stirring, the precipitated solid was filtered off with suction, washed with diethyl ether and dried under reduced pressure. 322 mg (88% of theory) of the target compound were obtained.
