4-benzyloxy-1-(3-fluorobenzyl)-1H-pyridin-2-one → HCID 54724162, compound

Participants

Reaction Steps

In a Fischer-Porter bottle, added a solution of 4-(benzyloxy)-1-(3-fluorobenzyl)pyridin-2(1H)-one (4.5 g, 14.56 mmol) in absolute ethanol (20 mL). Flushed the solution with nitrogen then added palladium catalyst (1.05 g, 10% Pd/C). Sealed bottle and evacuated system. The system was purged with hydrogen gas (2×15 psi) to check for leaks. The reaction was charged with hydrogen (35 psi) and stirred at room temperature for 45 minutes. The system was evacuated and flushed with nitrogen. The reaction was filtered and the catalyst was carefully washed with fresh ethanol. The filtrate was concentrated under reduced pressure 1H-NMR (CD3OD, 400 MHz) δ7.54 (d, 1H, J=7.6 Hz), 7.32 (m, 1H), 7.06 (d, 1H, J=7.6 Hz), 6.99 (m, 2H), 6.05 (dd, 1H, J=2.4 Hz, 2.8 Hz), 5.83 (d, 1H, J=2.4 Hz), 5.09 (s, 2H); ES-HRMS m/z 220.0774 (M+H calculated for C12H11NO2F requires 220.0787).
