Reaction Steps
A mixture of 10 g (0.17 mol) of glyoxal in 50 ml of water was added to 5 g (0.03 mol) of 2,3-diaminohydroquinone dimethyl ether, and stirred at 50° C. for 1 hour. After allowing to cool to room temperature, the reaction solution was extracted with chloroform, and the extract was dried and concentrated. Recrystallization of the residue from benzene gave 4.3 g (75%) of the title compound. m.p. 145°-150° C.
