Procedure
60 mg (0.068 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 N2, N5-bis(tert-butoxycarbonyl)-L-ornithinate (Example 20A) were initially charged in 1.8 ml dichloromethane. 0.211 ml (2.738 mmol) of trifluoroacetic acid was added, and the reaction solution was then stirred at RT overnight. The reaction solution was concentrated by evaporation and the residue was purified by preparative HPLC (acetonitrile/water+0.1% TFA). This gave 55 mg (89% of theory) of the target compound.
