Novel imidazothiazolotriazines were obtained as a result of the reaction of imidazo[4,5-e][1,2,4]triazine-3-thiones with various phenacyl bromides. It was shown that the cyclocondensation proceeds with high regioselectivity leading to the formation of linear 7-arylimidazo-[4,5-e]thiazolo[3,2-b][1,2,4]triazines.
