Reaction Steps
A mixture of 2-aminobenzothiazole (5.0 g., 0.033 mol) and diethyl oxalate (50 ml.) is heated at reflux for 2.5 hours. A white solid precipitates from the cooled reaction mixture. The solid is recrystallized from ethanol (with a hot filtration) to give the desired product (3.72 g., m.p. 185°-186°, 44%).
