실험 절차
(1RS,6SR)-8,8-dichlorobicyclo[4.2.0]octan-7-one (preparation 18) (8.60 g, 44.6 mmol) was heated to reflux in acetic acid (100 ml) with zinc dust (29.0 g, 446 mmol). After 4 hrs the mixture was cooled to room temperature, diluted with diethyl ether (200 ml) and washed with 2N NaOH (2×100 ml) and then with saturated aqueous NaHCO3 (4×100 ml). The ether phase was collected, dried (MgSO4) and the solvent was removed under reduced pressure to give 4.79 g of the title compound as a clear oil.
