실험 절차

At room temperature, 17 ml of a 12% strength aqueous sodium hypochlorite solution were added dropwise with vigorous stirring to a solution of 2.6 g (10 mmol) of methyl 2,4-dichloro-3-ethenylbenzoate and 1 g (10 mmol) of 2,2-dimethylpropionaldoxime in 100 ml of dichloromethane. Twice, in each case after 2 hours of stirring, a further 0.5 g (5 mmol) of the oxime and 9 ml of the hypochlorite solution were added. The reaction mixture was stirred at room temperature for a further 12 hours and then stirred into 350 ml of water. After extraction with dichloromethane, drying and removal of the solvent, the residue was chromatographed.
