New heterocyclic system namely 2,3-diacetoxy-6,7,11,12-tetrahydro-5H- benzo[3′,4′] cyclohepta[4,5]thieno[2,3-d]pyrimidin-12-one (7) have been synthesized via the reaction of 2-amino-8,9-diacetoxy-5,6-dihydro-4H- benzo[3,4]cyclohepta[e]thiophene-1-carbonitrile (6) intermediate with formic acid in presence of MCM-41(H), in good yield.

Reaction with lithium chloride in boiling dimethylformamide hes been shown to give high yields of 2,3-diacetoxybenzocyclohepten-5-one (4) from 2,3-diacetoxy-6,6-dibromo-6,7,8,9-tetrahydrobenzocyclohepten-5-one (3).Similar elimination occurs from 2,3-diacetoxy-6,9-dibromo-6,7,8,9-tetrahydrobenzocyclohepten-5-one (5) to give 4.
