Triethylamine → 2-((2S)-2-(4-(N-cyclohexyl-N-methylamino)-phenyl)morpholin-4-yl)-3-methyl-6-(4-pyridyl)-pyrimidin-4-one

Participants

Reaction Steps

To a solution of (2S)-2-(4-(N-cyclohexyl-N-methylamino)phenyl)morpholine (4.47 g, 16.30 mmol) and triethylamine (3.1 ml, 22.2 mmol) in tetrahydrofuran (50 ml) was added 2-chloro-3-methyl-6-(4-pyridyl)-3H-pyrimidin-4-one (3.28 g, 14.82 mmol) portionwise. Upon disappearance of the chloropyrimidone, the reaction mixture was condensed under reduced pressure. The residue was partitioned between 1 N sodium hydroxide and dichloromethane. The organic layer was washed with water, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to give a pale yellow solid, which was recrystallized from ethanol to afford 2-((2S)-2-(4-(N-cyclohexyl-N-methylamino)-phenyl)morpholin-4-yl)-3-methyl-6-(4-pyridyl)-pyrimidin-4-one (5.15 g, 75.7%) as white crystals.
