1-(2,4-Dichlorobenzyl)-7-(ethoxycarbonyl)-3-methyl-2(1H)-quinoxalinone (0.50 g) in a mixture of a 5% aqueous sodium hydroxide solution (3 g) and methanol (20 ml) was heated under reflux for 1 hr. After cooling, concentrated hydrochloric acid (4 ml) and water (10 ml) were added to the reaction mixture and the precipitate was collected by filtration.
