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 pyridine. 17 mg of acetic anhydride was added to the obtained solution, and they were stirred at room temperature for 16 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 reduce pressure, and the obtained residue was purified by the silica gel column chromatography (eluent: chloroform/ethyl acetate=4/1) to obtain 55 mg of ethyl 8-(4-acetylaminophenyl)-1-cyclopropyl-9-methyl-4-oxo-4H-quinolizine-3-carboxylate.
