Reaction Steps

363 mg of methyl 10-chloro-4-oxo-3-phenyl-4H-benzo[a]quinolizine-1-carboxylate were hydrogenated at room temperature in 50 ml of ethyl acetate in the presence of 36 mg of 10 percent palladium/carbon. The catalyst was removed by filtration and the solvent was removed in vacuo. The residue was purified by chromatography on silica gel and the product was crystallized from methanol. There was obtained methyl 10-chloro-6,7-dihydro-4-oxo-3 -phenyl-4H-benzo[a]quinolizine-1-carboxylate of m.p. 138°-139°.
