Reaction Steps

The reaction was carried out under argon. Allyl (4S)-4-[4-cyano-2-(methylsulfonyl)phenyl]-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxylate (800 mg, 1.54 mmol; Example 4) and morpholine (1.5 eq., 201 mg, 2.31 mmol) were initially charged in dry THF (25 ml) at RT. The reaction mixture was degassed repeatedly (evacuation followed by venting with argon). Under protective gas, tetrakis(triphenylphosphine)palladium(0) (0.05 eq., 89 mg, 0.077 mmol) was added, and the reaction mixture was stirred at RT for 90 min (HPLC control). The reaction mixture was then concentrated and the residue was taken up in ethyl acetate (500 ml). The organic phase was washed with saturated ammonium chloride solution (50 ml), with water (50 ml) and with conc. sodium chloride solution (50 ml), dried over sodium sulfate, filtered and concentrated under reduced pressure. 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 (696 mg, purity 86%, 81% of theory).
