Participants

Reaction Steps

Methyl chloroformate (0.13 g, 1.38 mmol) was added to a solution of 2-((2S)-2-(4-aminophenyl)morpholine-4-yl)-6-(3-fluoropyridin-4-yl)-3-methyl-3H-pyrimidin-4-one obtained in Example 13 (0.35 g, 0.92 mmol) and triethylamine (0.25 g, 2.47 mmol) in tetrahydrofuran (20 ml) and the solution was stirred at room temperature for one hour. The mixture was partitioned between water and chloroform. The organic layer was washed with brine, dried over magnesium sulfate, and concentrated in vacuo. The residue was purified by silica gel column chromatography eluting 5-10% methanol in chloroform to furnish methyl (4-((2S)-4-(6-(3-fluoropyridin-4-yl)-3-methyl-4-oxo-3H-pyrimidin-2-yl)morpholin-2-yl)phenyl)carbamate (0.17 g, 42%) as white crystals.
