2-Substituted oxazolo [b] quinoxaline with a new skeleton was synthesized by heating 2-amino-3-quinoxalinol with excess of acyl chlorides at 180∼210°, by boiling with three volumes of acyl chlorides in nitrobenzene, or by heating 2-acylamino-3-quinoxalinol with phosphoryl chloride. When the 2-substituted radical of oxazolo [b] quinoxaline is aliphatic, 2-substituted oxazolo [b] quinoxaline was not obtained but the compounds formed when the substituents were aromatic radicals. This problem is now under investigation.
