Abstract
Novel heterocyclic compound 10-Chloro-15-imino-14-oxo-14(H) benzothiazolo[2,3-b]pyrimido[5,6-e] pyrimido[2,3-b]benzothiazole and its 3-substituted derivatives were synthesized by reaction of 8-chloro-3-cyno- 2-methylthio-4-oxo-[4H]-pyrimido-(2,1-b) benzothiazole (1a)with 2-amino- 6- substituted benzothiazoles(2a-e).
