실험 절차

The reaction was carried out under argon. (4S)-4-[4-Cyano-2-(methylsulfonyl)phenyl]-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carbonitrile (69.1 mg, 150 μmol; Example 6) was initially charged in THF (2 ml), and sodium hydride (60% in mineral oil; 7.2 mg, 180 μmol) was added at 0° C. The mixture was warmed to RT and stirred for 20 min. A solution of methanesulfonyl chloride (20.6 mg, 180 μmol, 1.2 eq.) in THF (1 ml) was then slowly added dropwise. After a reaction time of 16 h, more methanesulfonyl chloride (6.7 mg, 60 μmol, 0.4 eq.) was added, and the mixture was again stirred at RT for 60 min. The reaction mixture was then 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 (47 mg, 58% of theory).
