Hydrochloric Acid → (2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)-acetone O-(3-(5-trifluoromethyl-2-pyridyloxy)propyl)oxime

Participants

Reaction Steps

A mixture of 0.34 g of (2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)-phenoxy)acetone, 0.24 g of O-(3-(5-trifluoromethyl-2-pyridyloxy)propyl)-hydroxylamine, 0.14 g of pyridinium chloride, and 10 ml of pyridine was stirred at room temperature for 2 hours. The reaction mixture was poured into diluted hydrochloric acid, and extracted twice with diethyl ether. The diethyl ether layers were combined, washed with water, dried over anhydrous magnesium sulfate, and concentrated to give a crude product. The crude product was subjected to silica gel chromatography, which afforded 0.40 g (yield, 71%) of (2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)phenoxy)-acetone O-(3-(5-trifluoromethyl-2-pyridyloxy)propyl)oxime, nD23.0 1.5310.
