## Abstract 4‐Amino‐6‐methyl‐3‐(2__H__)‐thioxo‐5‐(4__H__)‐oxo‐1,2,4‐triazine (**1**) was condensed with 2‐methyl (or phenyl)‐4__H__‐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
