실험 절차

To a mixture of 0.60 g of 4-(2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)butyloxyacetaldehyde, 0.29 g of zinc dust and 10 ml of N,N-dimethylformamide was added 0.040 g of trichloroacetonitrile with stirring at room temperature. After stirring at room temperature for 2 hours, the reaction mixture was poured into 10 ml of diluted hydrochloric acid and extracted twice with diethyl ether. The diethyl ether layers were combined, washed with water; dried over magnesium sulfate and then evaporated to give a crude product. The crude product was subjected to silica gel chromatography, which afforded 0.35 g of 3,5-dichloro-1-(3,3-dichloro-2-propenyloxy)-4-(4-(3-cyano-3,3-dichloro-2-hydroxypropyloxy)butyloxy)benzene (yield, 46%), nD24.0 1.5460.
