Synthesis of pyrido-thieno-pyrimidines and -triazines with an anellated dihydroimidazo- or tetrahydropyrimido moiety by the reaction of C1- or N1-components with tricyclic pyrido-thieno compounds

In a previous paper described 3-amino-2-(4,5-dihydroimidazole-2-yl)- and 3-amino-2-(3,4,5,6-tetrahydropyrimidine-2-yl)-thieno[2,3-b]pyridines D reacted with trimethyl orthoformiate or diethyl oxalate, respectively, to give the tetracyclic pyrimidine deriv
