Abstract The halogenation of 2,3-dimethylpyrazino[2,3-b][1,4]thiazin-6-one with bromine or 1 mole of sulfuryl chloride gives 7-bromo-and 7-chloropyrazino[2,3-b][1,4]thiazin-6-ones, while 2 moles of sulfuryl chloride give 7,7-dichloropyrazino[2,3-b][1,4]thiazin-6-one. A number of 7-amino-and 7,7-diaminopyrazino[2,3-b][1,4]thiazin-6-ones were obtained by the reaction of the appropriate halo derivatives with amines. Some of the pyrazino[2,3-b][1,4]thiazin-6-one derivatives inhibit the growth of interweavable tumors in animals.
