Participants

Conditions

Temperature: 180 °C

Procedure

A mixture of 0.20 g (0.38 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-[6-chloro-4-(4-fluoro-2-methyl-phenyl)-pyridin-3-yl]-N-methyl-isobutyramide, 0.23 g (2.3 mmol) L-prolinol and 0.15 g (1.1 mmol) potassium carbonate in 0.5 ml dimethyl sulfoxide was heated at 180° C. under microwave irradiation for 30 min. in a sealed tube. After cooling to room temperature the reaction mixture was diluted with water and extracted with three portions of tert-butyl methyl ether. The combined organic extracts were washed with water and brine, dried over sodium sulfate and concentrated in vacuo. Flash column chromatography gave 0.18 g (78%) of the title compound as an off-white solid.
