Versuchsvorschrift

A mixture of 11.0 g (20.6 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-[6-chloro-4-(4-fluoro-2-methyl-phenyl)-pyridin-3-yl]-N-methyl-isobutyramide, 14.3 g (103 mmol) potassium carbonate and 12.2 g (75.7 mmol) (2R,3S)-2-(hydroxymethyl)-3-hydroxypyrrolidine in 110 ml dimethyl sulfoxide was stirred at 130° C. for 68 h. The reaction mixture was diluted with 800 ml ethyl acetate and washed with 800 ml saturated sodium carbonate solution, 500 ml water and 750 ml brine. The combined aqueous layers were extracted with two 800-ml portions of ethyl acetate. The combined organic layers were dried over sodium sulfate and concentrated in vacuo. Purification by flash chromatography gave 8.48 g (67%) of the title compound as a light yellow foam.
