Procedure

The reaction was carried out under argon. 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-carbonitrile (550 mg, 0.909 mmol) was initially charged in dichloromethane (30 ml), trifluoroacetic acid (30 ml) was added and the mixture was stirred at RT for 5 h (HPLC control). The mixture was then concentrated without heating, and the residue was taken up in dichloromethane (200 ml). The organic phase was washed with saturated sodium bicarbonate solution (2×50 ml) and with saturated sodium chloride solution (50 ml), dried over solid sodium sulfate, filtered and concentrated under reduced pressure. The oil obtained was taken up in a little acetonitrile, water was added and the mixture was lyophilized. The title compound was obtained as a solid (450 mg, quant.).
