Reaction Steps

To a solution of 1-(4-methoxybenzyl)-4-hydroxyethyl-3-nitro-2-pyridone (0.35 g, 1.2 mmol) in pyridine (4 mL) was added benzenesulfonyl chloride (0.2 mL). After 4 days, the mixture was diluted with ethyl acetate, and washed with dilute hydrochloric acid. The aqueous phase was basified to pH 13 with aqueous KOH, and after 30 minutes was extracted with ethyl acetate. The organic phase was dried, filtered and evaporated to give 1-(4-methoxybenzyl)-4-vinyl-3-nitro-2-pyridone (0.29 g, 1.0 mmol, 83%).
