The synthesis of a polycyclic heterocyclic ring system compound, ethyl 7-hydroxy-4-oxo-2-phenyl-4,5-dihydro-3H-benzo[6,7]cyclohepta[1,2-d]pyrimidine-6-carboxylate was carried out by condensation of benzamidine on diethyl 5,9-dihydroxy-7H-benzo[a]cycloheptene-6,8-dicarboxylate, after opening and then closure of the seven membered ring.
