S-acetals, and oxallyl chloride to give thienopyrimidines 2-6 and thieno-1,4-diazepine 7 . Treatment of compound 1 with nitrous acid afforded compound 8 , which converted into the corresponding chloro derivative 9 by using PCl 5 . Compound 9 was reacted with amino reagents to afford the corresponding thienoimidazotriazines 10 and 11 , thienotriazolotriazines 12 and 13 and 4-hydrazinothienotriazine 14 . Treatment
