Morpholine → HCID 58133803, compound

Participants

Reaction Steps

The reaction was carried out under argon. Allyl (4S)-4-[4-cyano-2-(methylsulfonyl)phenyl]-3,6-dimethyl-2-oxo-1-[3-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimidine-5-carboxylate (157 mg, 0.294 mmol) and morpholine (1.5 eq., 38 mg, 0.441 mmol) were initially charged in dry THF (5 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., 17 mg, 0.015 mmol) was added, and the reaction mixture was stirred at RT for 16 h (HPLC control). The mixture was then concentrated under reduced pressure, and the residue was purified by preparative HPLC (column: Gromsil C-18; mobile phase: acetonitrile/water+0.1% TFA 10:90→90:10). This gave the title compound as a solid (120 mg, 83% of theory).
