실험 절차

A solution of 19 parts of 2-acetamido-3-aminoquinoxaline in 200 parts of glacial acetic acid was heated at reflux for 30 minutes. Concentration in vacuo left a pale yellow solid. Recrystallization from ethyl acetate-methanol (2:1) gave 16.8 parts of pale yellow 2-methyl-1H-imidazo[4,5-b]quinoxaline, mp 360° (dec.).
