Procedure

To a solution of 1.24 g (2.24 mmol) N-(3,5-bis-trifluoromethyl-benzyl)-N-methyl-6-thiomorpholin-4-yl-4-o-tolyl-nicotinamide (step a)) in 25 ml methanol were added 689 mg (1.12 mmol) Oxone® at 0° C. After completed addition the reaction mixture was allowed to warm to room temperature and stirred for 1.5 h. Quenching with 5 ml 40% aqueous sodium hydrogen sulfite solution was followed by addition of 6 ml 1N sodium hydroxide solution to adjust the pH to 7-8. The mixture was diluted with 50 ml water and extracted with 3 150-ml portions of dichloromethane. The combined extracts were dried with sodium sulfate and concentrated to give 1.20 g of crude product. Flash chromatography afforded 1.02 g (79.9%) of the title compound as a white solid.
