Reaction Steps

Under an atmosphere of argon protective gas, 5-cyano-2-{(4S)-5-cyano-3,6-dimethyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidin-4-yl}benzenesulfonyl chloride (50 mg, 101 μmol) was dissolved in absolute THF (2.5 ml), diethanolamine (29 μl, 303 μmol; 3 eq.) and triethylamine (10.2 mg, 101 μmol; 1 eq.) were added at room temperature and the mixture was stirred overnight. The reaction mixture was then concentrated under reduced pressure and the residue was purified by preparative HPLC (column: Gromsil C-18, 10 μm; mobile phase: acetonitrile/water+0.1% TFA 10:90→90:10). This gave a colorless amorphous solid (4.9 mg, 9% of theory).
