ABSTRACT:
A mixture of 6-nitro-2-hydrazino benzothiazole (I) on heated with diethyl oxalate (II) in presence of pyridine gives 3,4-dihydro-8-nitro-2H-1,2,4-triazino[3,4-b] benzothiazole-3,4-dione (III). Which on further reaction with different heteryl amines such as morpholine, pyrrolidine and piperidine afforded Mannich bases (IV a-c).
KEYWORDS:
