Reaction Steps

A mixture of 13.6 g of 2-methyl-2,3-dihydro-8H-3a, 8-methanodibenzo[3,4:6,7]cyclohepta[1,2-c]pyrrole, 100 ml of acetic acid and 2 g of 10% palladium-on-charcoal catalyst is shaken under 40 psi hydrogen pressure at room temperature until the pressure remains constant. The filtered mixture is concentrated, the residue is made basic and extracted several times with methylene chloride. Removal of the solvent from the dried extracts gives 13.7 g of 2-methyl-2,3,8,12b-tetrahydro-1H-3a,8-methanodibenzo[3,4;6,7]-cyclohepta[1,2-c]pyrrole (1c) identical by nmr spectroscopy with the product obtained in Example 1.
