Reaction Steps

To a mixture of 4-(1-methylpropoxy)phenoxyacetaldehyde (0.68 g, 3.3 mmol) and pyridine (0.50 g, 6.3 mmol) in 5 ml of p-dioxane is added a solution of ethoxyamine hydrochloride (0.60 g, 6.2 mmol) in a minimum amount of water. The reaction mixture is stirred at RT for 6 hours, after which the dioxane is removed in vacuo. The residue is taken up in ether and the organic layer is washed with water. The aqueous phase is extracted with ether, and the combined organic phases are dried, the solvent is removed in vacuo and the product is purified by column chromatography to give 4-(1-methylpropoxy)phenoxyacetaldehyde O-ethyloxime as a mixture of syn and anti stereo isomers. MS m/e 251 (M+).
