4-Amino-6-methyl-3-(2H)-thioxo-5-(4H)-oxo-1,2,4-triazine (1) was condensed with 2-methyl (or phenyl)-4H-3,1-benzoxazin-4-one (5a,b) in boiling acetic acid to give compounds 8-11. Reacting 1 with chloroacetyl chloride afforded the corresponding chloroacetamido and triazinothiadiazine derivatives 12 and 13. Condensing 2 with succinic anhydride and/or phthalic anhydride yielded compounds 14 and 15. Benzoylation
