Procedure

A mixture of 0.5 g of ethyl 8,9-difluoro-6-oxo-6H-benzo[c]quinolizine-5-carboxylate and 0.5 g of 10% palladium-on-carbon in 50 ml of trifluoroacetic acid was shaken under 40 lb. of hydrogen in a Parr apparatus for 2 hours. The mixture was filtered and the solvent evaporated. The concentrate was partitioned between aqueous sodium bicarbonate and dichloromethane. The organic layer was dried followed by adding hexanes to give 0.45 g of the desired product, mp 166°-168° C.
