反应详情

A stirred suspension of 0.25 g. (0.84 mmol.) of 2-benzoyl-3-hydroxymethylquinoxaline 1,4-dioxide, in 10 ml. of methanol, was saturated with dry hydrogen chloride. The reaction mixture was stirred at room temperature overnight and then the suspended solid was collected by filtration. This afforded 0.16 g. (60% yield) of 1-methoxy-1-phenyl-1,3-dihydrofuro[3,4-b]quinoxaline 4,9-dioxide, m.p. 150°-151° C.
