Versuchsvorschrift
To 4-(4-(benzyloxy)-2-oxopyridin-1(2H)-yl)-3-fluorobenzonitrile (250 mg, 0.780 mmol) and 10% palladium on carbon (50 mg, 0.470 mmol) was applied vacuum then placed under an atmosphere of nitrogen. Methanol (5 mL) was added and vacuum applied briefly. The reaction was placed under an atmosphere of hydrogen for 6 hours. The reaction mixture was passed through a 10×10 mm CELITE® 545 filter aid plug eluting with an additional 10 mL each of MeOH and CH2Cl2. The filtrate was concentrated to 170 mg of a pale tan foam. Added 5 mL MeOH and heated to reflux, filtered hot and rinsed with 3×2 mL warm MeOH. The filtrate was concentrated to crude product (166 mg, 0.577 mmol, 74%) as a pale yellow solid which was used as obtained in the subsequent step. MS (ESI) 231.1 (M+1).
