Cyclocondensation of 2-aminobenzimidazole with unsaturated ketones or the hydrochlorides of Mannich bases has yielded aromatic substituted 1,4(3,4)-dihydropyrimidobenzimidazoles.The dependence of the tautomer composition of the products on steric factors and on the electronic character of the substituents introduced has been studied.
