A facile synthesis of the imidazo[1,5-d]thieno[2,3-b][1,4]thiazine ring system is described. Reaction of 6- benzyl-2,3-dihydro-1H-thieno[2,3-b][1,4]thiazine-2-one (1) with potassium tert-butoxide and diethylchlorophosphate gave intermediate 2 which resulted in the disired ring system after adding the corresponding isocyanides and potassium tert-butoxide.
