Participants

Reaction Steps

To a solution of 0.05 g of 6-formyl-3-(p-methoxybenzyl)oxy-4-pyridone in 5 ml of pyridine is added 0.133 g of acetic anhydride, and the mixture is stirred for 2 hours. The reaction mixture is condensed under reduced pressure, and the residue is dissolved in 20 ml of methylene chloride, washed with water, 5% aqueous potassium hydrogen sulfatge solution and 7% aqueous sodium hydrogen carbonatge solution in this sequence, dried over magnesium sulfate, and condensed to dryness under reduced pressure to give 0.318 g of the title compound as colorless crystal.
