Tetracyclic azanaphthalen-8-ones are synthesized by condensing 3-bromo-4-methyl benzo[h]-chromen-2-one with different primary aromatic amines. 3-Bromo-4-methylbenzo[h]chromen-2-one is synthesized by bromination of 4-methylbenzo[h]chromen-2-one using N-bromosuccinimide. Condensation of 3-bromo-4-methylbenzo[h]chromen-2-one with different secondary cyclic amines gave tetracyclic oxa-naphthalen-9-one
