ABSTRACT:
2-Amino-6-nitrobenzothiazole is obtained with a high selectivity if, instead of unprotected 2-aminobenzothiazole, acylation products thereof are nitrated and the acyl groups are then split off. 2-Amino-6-nitrobenzothiazole is an important intermediate product for the preparation of valuable azo dyestuffs.
