To a solution of 600 mg (1.03 mmol) (S)-N-[6-(3-amino-pyrrolidin-1-yl)-4-(4-fluoro-2-methyl-phenyl)-pyridin-3-yl]-2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-isobutyramide in 6 ml dichloromethane were added 6 mg (0.05 mmol) 4-(N,N-dimethylamino)pyridine, 266 mg (2.06 mmol) N,N-diisopropylethylamine and 153 mg (1.34 mmol) methanesulfonyl chloride. After stirring at room temperature for 18 h the reaction mixture was diluted with 20 ml dichloromethane and washed with 20 ml of a saturated aqueous solution of sodium carbonate. The combined organic layers were dried over sodium sulfate, concentrated and purified by flash chromatography to give 553 mg (81%) of the title compound as an off-white foam.
