Versuchsvorschrift

39 mg (0.053 mmol) of 2-{4-(2-(azetidin-1-yl)-6-({(2-(4-chlorophenyl)-1,3-thiazol-4-yl)methyl}sulfanyl)-3,5-dicyanopyridin-4-yl)phenoxy}ethyl N-(tert-butoxycarbonyl)-L-alaninate (Example 13A) were initially charged in 1.5 ml dichloromethane. 0.5 ml (6.49 mmol) of trifluoroacetic acid was added, and the reaction solution was then stirred at RT for 1.5 h. The reaction solution was concentrated by evaporation and the residue was purified by preparative HPLC (acetonitrile/water+0.1% TFA). This gave 40 mg (100% of theory) of the target compound.
