Procedure

A mixture of 0.15 g (0.28 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-[6-chloro-4-(4-fluoro-2-methyl-phenyl)-pyridin-3-yl]-N-methyl-isobutyramide, 0.13 g (0.84 mmol) 8-oxa-3-aza-bicyclo[3.2.1]octane hydrochloride and 0.20 g (1.4 mmol) potassium carbonate in 1 ml dimethyl sulfoxide was heated at 150° C. under microwave irradiation in a sealed tube for 30 min. Another portion of 0.06 g (0.4 mmol) 8-oxa-3-aza-bicyclo[3.2.1]octane hydrochloride was added and the reaction mixture was heated at 150° C. under microwave irradiation in a sealed tube for 30 more minutes. After cooling to room temperature the reaction mixture was diluted with water and extracted with four portions of tert-butyl methyl ether. The combined organic extracts were dried over sodium sulfate and concentrated. Flash column chromatography gave 32 mg (18%) of the title compound as a light yellow solid.
