Participants

Reaction Steps

To a solution of 44 mg (0.33 mmol) 1,1,3,3-tetramethyl-2-thiourea in 1.5 ml N,N-dimethylformamide were added 0.027 ml iodomethane at room temperature. After stirring for 50 min. 0.20 g (0.33 mmol) (S)-2-(3,5-bis-trifluoromethyl-phenyl)-N-[4-(4-fluoro-2-methyl-phenyl)-6-(2-hydroxymethyl-pyrrolidin-1-yl)-pyridin-3-yl]-N-methyl-isobutyramide and a suspension of 45 mg (0.90 mmol) sodium hydride (ca. 50% dispersion in mineral oil) in 0.5 ml n-hexane were added. After stirring at room temperature for 1 h the reaction mixture was diluted with water and extracted with three portions of tert-butyl methyl ether. The combined organic extracts were dried over sodium sulphate and concentrated. Flash column chromatography gave 90 mg (40%) of the title compound as an off-white solid.
