| Product | 2-{4-(2-({(2-(4-Chlorophenyl)-1,3-thiazol-4-yl)methyl}sulfanyl)-3,5-dicyano-6-(propyl-amino)pyridin-4-yl)phenoxy}ethyl L-alaninate trifluoroacetate | HCID 46850940 | — |
Reaction Steps
873 mg (1.191 mmol) of 2-{4-(2-({(2-(4-chlorophenyl)-1,3-thiazol-4-yl)methyl}sulfanyl)-3,5-dicyano-6-(propylamino)pyridin-4-yl)phenoxy}ethyl N-(tert-butoxycarbonyl)-L-alaninate (Example 14A) were initially charged in 29 ml of dichloromethane. 1.84 ml (23.817 mmol) of trifluoroacetic acid were added, and the reaction solution was then stirred at RT overnight. The reaction solution was concentrated by evaporation and the residue was triturated with diethyl ether. The solid formed was filtered off and dried. This gave 914 mg (89% of theory) of the target compound.
