Reaction Steps

A suspension of 30.0 g. (0.11 mol.) of 2-acetyl-3-acetoxymethylquinoxaline 1,4-dioxide in 300 ml. of methanol, saturated with dry hydrogen chloride, was stirred at ambient temperature for 2 days. The tan solid was collected by filtration, and then it was recrystallized from methanol, to give 17.0 g. (63% yield) of 1-methoxy-1-methyl-1,3-dihydrofuro[3,4-b]quinoxaline 4,9-dioxide, m.p. 201°-202° C.
