We have studied the reaction of 2-aminobenzimidazole with esters of substituted cinnamic acids and arylidene derivatives of Meldrum's acid, and have established the direction of formation of the tetrahydrooxopyrimidine ring. We have conducted an X-ray diffraction study of 2-phenyl-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazol-4-one.
