To 20 ml (387 m mole) of liquid bromine was added 10 g (48 m mole) of tricyclo[4.3.1.12,5 ]undecane and the resulting mixture was stirred at room temperature for 17 hours. To a cooled saturated sodium hydrogen sulfite solution was added dropwise with stirring the reaction mixture to remove excess bromine. This aqueous solution was extracted twice with a portion of 200 ml of carbon tetrachloride, and the extract was dried over magnesium sulfate. The carbon tetrachloride was evaporated to obtain 19 g of the residue, which was distilled under reduced pressure, and the fraction having a boiling point of 96° to 98° C./2 mmHg was collected. This was a colorless crystalline material having a melting point of 57.5° to 58.5° C.
