Procedure

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-carboxylic acid (696 mg, 1.45 mmol; Example 5A) and HATU (2 eq., 1104 mg, 2.9 mmol) were initially charged in dry DMF (35 ml) at 0° C., and after brief stirring (20 min) ammonium chloride (5 eq., 388 mg, 7.26 mmol) and DIEA (7 eq., 1314 mg, 10.16 mmol) were added. The mixture was stirred at RT for 4 h (monitored by HPLC). The mixture was then concentrated, 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 (612 mg, 88% of theory).
