Reaction Steps
6,7-Dimethoxy-1,4-dihydroquinoxaline-2,3-dione was prepared from 1,2-dimethoxybenzene. Nitration of 1,2-dimethoxybenzene gave 1,2-dimethoxy-4,5-dinitrobenzene, which was reduced to 1,2-diamino-4,5-dimethoxybenzene. Condensation of the diamine with oxalic acid gave 6,7-dimethoxy-1,4-dihydroquinoxaline-2,3-dione. ##STR31##
