A solution of 4-(benzyloxy)pyridin-2(1H)-one (9.92 g, 49.3 mmol), methyl iodide (4.60 mL, 74.0 mmol) and silver carbonate (13.6 g, 49.3 mmol) in chloroform (50 mL) was stirred with heating under reflux for four hours. After leaving to cool, the insoluble matter was separated by filtration and the filtrate was concentrated under reduced pressure. Then, the residue was purified by silica gel chromatography (hexane/ethyl acetate, 2:1) to obtain the title compound (4.65 g, 44%) as a pale yellow oil.
