実験手順

To a mixture of 0.14 g of 4-(trifluoromethyl)benzaldehyde and 10 ml of pyridine was added 0.30 g of O-(4-(2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)butyl)hydroxylamine hydrochloride. After stirring at room temperature for 1 hour, the reaction mixture was poured into 5% aqueous citric acid solution, and extracted twice with ethyl acetate. The ethyl acetate layers were combined, washed with water, dried over anhydrous magnesium sulfate, and concentrated to give a crude product. This crude product was subjected to silica gel chromatography, which afforded 0.37 g (yield, 95.6%) of 4-(trifluoromethyl)benzaldehyde O-(4-(2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)butyl)oxime, nD21.0 1.5387.
