Procedure

The reaction was carried out under argon. (rac)-4-[4-Cyano-2-((2-hydroxyethyl)sulfonyl)phenyl]-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid (910 mg, 1.79 mmol) and HATU (5 eq., 3396 mg, 8.9 mmol) were initially charged in dry DMF (20 ml) at 0° C., and ammonium chloride (5 eq., 478 mg, 8.9 mmol) and DIEA (10 eq., 2309 mg, 17.9 mmol) were added after brief stirring (20 min). The mixture was stirred at RT for 16 h (HPLC control) and then concentrated under reduced pressure. The crude product was purified by preparative HPLC (column: Gromsil C-18; mobile phase: acetonitrile/water+0.1% TFA 10:90→80:20). The title compound was obtained as a solid (740 mg, 81% of theory).
