Procedure

The reaction was carried out under argon. 2-[(6S)-5-Cyano-6-[4-cyano-2-(methylsulfonyl)phenyl]-4-methyl-2-oxo-3-[3-(trifluoromethyl)phenyl]-3,6-dihydropyrimidin-1(2H)-yl]acetic acid (45 mg, 87 μmol; Example 21) was initially charged in DMF (1.5 ml), HATU (165 mg, 434 μmol, 5 eq.) was added at 0° C. and the mixture was stirred for 20 min. 4-Hydroxypiperidine (43.9 mg, 434 μmol, 5 eq.) and N,N-diisopropylethylamine (56 mg, 434 μmol, 5 eq.) were then added, and the mixture was stirred at RT for 16 h until complete conversion had been achieved (HPLC control). The reaction mixture was then concentrated under reduced pressure, and the crude product was purified by preparative HPLC (column: Gromsil C-18 10 μm; mobile phase: acetonitrile/water+0.1% TFA 10:90→90:10). This gave the title compound as a colorless solid (51 mg, 98% of theory).
