실험 절차
15.9 g (81 mmol) of 7-Bromo-bicyclo[2.2.1]heptane were added dropwise to 2 g magnesium (81 mmol) in 25 ml of diethyl ether and refluxed for 2.5 h. The mixture was cooled to 0-5° C. and 6.3 ml (81 mmol) of DMF were added dropwise. The mixture was then refluxed for 2 h, cooled to room temperature and the white solid filtered off and washed with ether. The filtrate was reduced and 4.87 g of a white solid were obtained. The intermediate was used without further characterization.
