POLYMETHYLENE DYES FROM 2-METHYLINDOLO(3,2-B)THIAZOLO(5,4-D)QUINOXALINES HAVING SUBSTITUENTS AT THE NITROGEN ATOM OF THE INDOLE RING
Condensation of isatin with N-methylisatin, N-ethyl, N-propyl, N-butyl, N-phenyl, N-benzoyl and 5-nitroisatin with 2-methyl 5,6-diaminobenzthiazole gave 2-methyl-indolo(3,2-b)thiazolo(5,4-d)quinoxalines with a substituted nitrogen atom in the indole ring. When they are heated with alkyltosylates, q...
