Abstract
2-Aminobenzoxazole and a series of its N-substituted derivatives were prepared by the reaction of potassium benzoxazole-2-sulfonate with ammonia and various amines; some 6-nitro- and 6-acetamido-2-aminobenzoxazoles were also obtained. The reaction of 6-nitro-2-mercaptobenzoxazole with heterocyclic amines involves the initial formation of salt-like compounds with the mercapto-group, with subsequent elimination of hydrogen sulfide. Nitration of 2-aminobenzoxazole yields a mixture of 6-nitro-2-aminobenzoxazole and 6-nitro-2-nitraminobenzoxazole.
