Procedure

39 mg of ethyl 1-cyclopropyl-9-methyl-8-(3-nitrophenyl)-4-oxo-4H-quinolizine-3-carboxylate (Example 13) was dissolved in 2 ml of ethanol. 5 mg of 5% palladium carbon was added to the obtained solution, and they were stirred at room temperature in hydrogen atmosphere for 14 hours. The catalyst was taken by the filtration. Water was added to the filtrate. After the extraction with chloroform, the organic layer was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by the silica gel column chromatography (eluent: chloroform/methanol=100/1) to obtain 22 mg of ethyl 1-cyclopropyl-8-(3-ethylaminophenyl)-9-methyl-4-oxo-4H-quinolizine-3-carboxylate.
