3-b]quinoxaline 3 was synthesized and allowed to react with chloroacetyl chloride to give N-chloroacetyl derivative 4. Cyclization of 4 into the title compund 5 was achieved in boiling acetic anhydride. Reactions of 5 with morpholine and diethylamine afforded pyrimidinones 6 and 7. Reaction of 3 with sulfurylchloride, thionylchloride and nitrous acid gave thiadiazine derviatives 8 and 9 and triazinothienoquinoxaline
