Reaction Steps

To a suspension of 2.51 g (8.96 mmol) 3-benzyloxy-5-bromo-1H-pyridin-2-one and 2.48 g (17.9 mmol) K2CO3 in 45 mL DMF was added 1.12 mL (17.9 mmol) iodomethane at room temperature. After stirring overnight, 150 mL water was added with vigorous stirring causing precipitation of the product which was collected by filtration and dried in vacuo affording 2.3 g (87%) 3-benzyloxy-5-bromo-1-methyl-1H-pyridin-2-one
