Reaction Steps

50 mg of ethyl 8-(4-aminophenyl)-1-cyclopropyl-9-methyl-4-oxo-4H-quinolizine-3-carboxylate (Example 2) was dissolved in 2 ml of DMF. 20 mg of methyl iodide and 29 mg of potassium carbonate were added to the obtained solution, and they were stirred at 70° C. for 17 hours. Water was added to the reaction mixture. After the extraction with chloroform, the organic layer was dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the obtained residue was purified by the silica gel column chromatography (eluent: chloroform/ethyl acetate=9/1) to obtain 16 mg of ethyl 1-cyclopropyl-9-methyl-8-(4-methylaminophenyl)-4-oxo-4H-quinolizine-3-carboxylate.
