General 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 following
  • 2-amino-6-arylbenzothiazole compounds:
  • 6-p-tolylbenzo[d]thiazole-2-amine
  • 6-(4chlorophenyl)benzo[d]thiazole-2-amine
  • 6-(4-methoxyphenyl)benzo[d]thiazole-2-amine
  • 6-(3,5-bis(triflouromethyl)phenyl)benzo[d]thiazole-2-amine
  • 6-phenylbenzo[d]thiazole-2-amine
It may be employed as a ligand (L) in the synthesis of organometallic derivatives of Rh(I) [Rh(CO)2(L)(Cl)].
