Reaction Steps

The reaction was carried out under argon. Allyl(rac)-4-[4-cyano-2-((2-hydroxyethyl)sulfonyl)phenyl]-6-methyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxylate (150 mg, 0.273 mmol) and morpholine (1.5 eq., 35.6 mg, 0.409 mmol) were initially charged in dry THF (4 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., 15.8 mg, 0.014 mmol) was added, and the reaction mixture was stirred at RT for 1 h (HPLC control). The mixture was then concentrated, and the residue was taken up in ethyl acetate (60 ml). The organic phase was washed repeatedly with saturated ammonium chloride solution (3×20 ml), water (20 ml) and saturated sodium chloride solution (20 ml), dried over sodium sulfate, filtered and 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 (60 mg, 43% of theory).
