To a solution of 0.20 g (0.36 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-[4-(2-chloro-phenyl)-6-(2-hydroxy-ethylamino)-pyridin-3-yl]-N-methyl-isobutyramide in a 5 ml dichloromethane were added consecutively 0.11 g (1.1 mmol) triethylamine and 0.05 g (0.4 mmol) thionyl chloride at room temperature. After 1 h the reaction mixture was diluted with water and extracted with three portions of dichloromethane. The combined organic extracts were dried over sodium sulfate and concentrated in vacuo. Flash column chromatography gave 0.17 g (77%) of the title compound as a white solid.
