Procedure

The reaction was carried out under argon. (rac)-4-{2-[(2-{[tert-Butyl(dimethyl)silyl]oxy}ethyl)sulfonyl]-4-cyanophenyl}-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxamide (740 mg, 1.18 mmol) was initially charged in dry THF (30 ml), methoxycarbonylsulfamoyltriethylammonium hydroxide (Burgess reagent; 1.699 g, 7.13 mmol; 6 eq.) was added and the mixture was stirred at RT. After 75 min, HPLC control showed complete conversion. The reaction mixture was then taken up in ethyl acetate (150 ml). The organic phase was washed with saturated sodium chloride solution (3×50 ml), dried over solid sodium sulfate, filtered and concentrated. The residue was subjected to flash chromatography on silica gel (mobile phase: cyclohexane/ethyl acetate 1:1). The title compound was obtained as a colorless solid (550 mg, 77% of theory).
