Silver oxide (15 g) was added to a solution of 2,3-dimethoxy-5-methyl-6-morpholinomethylhydroquinone (9 g) as obtained in Reference Example 8 in ether-dioxane (5:2, 70 ml) and the mixture was stirred at room temperature for 1.5 hours. The filtrate was treated in the conventional manner and the residue was recrystallized from ethyl acetate-hexane to give 2,3-dimethoxy-5-methyl-6-morpholinomethyl-1,4-benzoquinone (4.5 g), melting at 60°-62° C.
