Reaction Steps

327 mg of ethyl 1-cyclopropyl-8-(4-hydroxymethylphenyl)-9-methyl-4-oxo-4H-quinolizine-3-carboxylate (Example 51) was dissolved in 11 ml of dichloromethane. 380 mg of carbon tetrabromide was added to the obtained solution, and they were cooled to 0° C. 355 mg of triphenylphosphine was added to the reaction mixture, and they were stirred for 30 minutes. The reaction mixture was concentrated under reduced pressure. The obtained residue was purified by the silica gel column chromatography (eluent: hexane/ethyl acetate=1/1) to obtain 291 mg of ethyl 8-(4-bromomethylphenyl)-1-cyclopropyl-9-methyl-4-oxo-4H-quinolizine-3-carboxylate.
