Description
Reaction of 4-bromoaniline with acetic acid and potassium thiocynate in solution of bromine in acetic acid yields 2-amino-6-bromobenzothiazole. 2-Amino-6-bromobenzothiazole can also be synthesized from 2-aminobenzothiazole via monobromination with silica-supported quinolinium tribromide. Application：2-Amino-6-bromobenzothiazole may be used in the synthesis of the following2-amino-6-arylbenzothiazole compounds:6-p-tolylbenzo[d]thiazole-2-amine6-(4chlorophenyl)benzo[d]thiazole-2-amine6-(4-methoxyphenyl)benzo[d]thiazole-2-amine6-(3,5-bis(triflouromethyl)phenyl)benzo[d]thiazole-2-amine6-phenylbenzo[d]thiazole-2-amine
