Procedure

A solution of 20.8 parts of acetic anhydride in 100 parts of tetrahydrofuran was added to a slurry of 24.0 parts of 2,3-diaminoquinoxaline in 900 parts of tetrahydrofuran. The heterogeneous reaction mixture was stirred at 25° for 20 hrs and then concentrated in vacuo to give 25 parts of 2-acetamido-3-aminoquinoxaline, mp 319° (dec.).
