実験手順

The reaction was carried out under argon. (4S)-4-[4-Cyano-2-(methylsulfanyl)phenyl]-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxamide (95.0 mg, 0.213 mmol) was dissolved in THF (4 ml), and methoxycarbonylsulfamoyltriethylammonium hydroxide (Burgess reagent; 101 mg, 0.426 mmol) was added. After 30 min of stirring at room temperature, HPLC showed complete conversion. The mixture was diluted with ethyl acetate (4 ml), and water (1 ml) was added. The mixture was then applied to a Merck Extrelut® NT3 column and the filtrate was purified by preparative HPLC. Concentration of the product fractions gave 96.0 mg (quant.) of the title compound.
