Procedure
A mixture of 0.25 g (0.47 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-[6-chloro-4-(4-fluoro-2-methyl-phenyl)-pyridin-3-yl]-N-methyl-isobutyramide and 0.59 g (6.6 mmol) thiazolidine was heated three times at 180° C. for 30 minutes and once at 250° C. for 15 minutes under microwave irradiation in a sealed tube. The reaction mixture was diluted with a 0.2 M aqueous solution of sodium hydroxide and extracted with three portions of tert-butyl methyl ether. The combined organic extracts were dried over sodium sulfate and concentrated in vacuo. Flash column chromatography and drying in high vacuo (70-90° C./1-2 mbar) for three hours gave 33 mg (12%) of the title compound as a yellow oil.
