Reaction Conditions

Reaction Steps

In an atmosphere of argon, metallic sodium (230.0 mg, 0.01 g atom) was dissolved in methanol (10.0 ml) at room temperature, a methanol solution (10.0 ml) of 2-chloro-3-cyano-6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridine (1.03 g, 5.00 mmol) was added dropwise thereto at the same temperature and then the resulting mixture was stirred at 60° C. for 6 hours. After cooling, methanol was evaporated under reduced pressure, the thus obtained residue was mixed with water and extracted with chloroform, and the resulting organic layer was washed with water and saturated brine in that order and dried over anhydrous sodium sulfate. After evaporation of the solvent under reduced pressure, the resulting residue was purified by a silica gel column chromatography (methylene chloride:hexane=2:1) to obtain the title compound (933.8 mg, 92.5%) as white powder.
