실험 절차

Various processes for the preparation of 2-amino-6-nitrobenzothiazole are known. For example Pubbl. ist. chim. univ. Bologna No. 2, 3-10 (1943); Chemical Abstracts 41:754 discloses the chlorination of 2-mercaptobenzothiazole to give 2-chlorobenzothiazole which is then treated with nitric and sulfuric acids to give 2-chloro-6-nitrobenzothiazole. The 2-chloro-6-nitrobenzothiazole is then treated with alcoholic ammonia under pressure at 140° to give 2-amino-6-nitrobenzothiazole. No yields are stated in the English abstract.
