Procedure

The reaction was carried out under argon. (4S)-4-[4-Cyano-2-(ethylsulfonyl)phenyl]-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (71.2 mg, 150 μmol) was initially charged in dry THF (3 ml), and sodium hydride (60% in mineral oil; 8.4 mg, 210 μmol; 1.4 eq.) was added at 0° C. The mixture was warmed to RT and stirred for 20 min. A solution of methanesulfonyl chloride (24.1 mg, 210 μmol; 1.4 eq.) in THF (1 ml) was then slowly added dropwise. After a reaction time of 20 h, the reaction mixture was concentrated and the crude product was purified by preparative HPLC (column: Gromsil C-18 10 μm; mobile phase: acetonitrile/water+0.1% TFA 10:90→80:20). This gave the title compound as a colorless solid (70 mg, 84% of theory).
