Procedure

The reaction was carried out under argon. (rac)-4-{4-Cyano-2-[(1-methylethyl)sulfonyl]phenyl}-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid (1000 mg, 1.97 mmol) and HATU (3 eq., 2248 mg, 5.9 mmol) were initially charged in dry DMF (25 ml) at 0° C., and a 0.5 M solution of ammonia in dioxane (3 eq., 11.8 ml, 5.9 mmol) and DIEA (3 eq., 764 mg, 5.9 mmol) were added after brief stirring (20 min). The mixture was stirred at RT for 6 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 (750 mg, 75% of theory).
