68 ml of thionyl chloride was added dropwise to 46.0 g (0.24 mole) of 1-carboxytricyclo[4.3.1.12,5 ]undecane dissolved in 200 ml of benzene at room temperature. The resulting mixture was refluxed for 1.5 hours, and the excess thionyl chloride and benzene were distilled off under reduced pressure. The residue obtained was fractionally distilled under reduced pressure to afford 47.0 g (yield: 92%) of 1-chorocarbonyltricyclo[4.3.1.12,5 ]undecane having a boiling point of 101° c. (1 mmHg).
