実験手順

In a solution of 64 mg of 4-formyl-N-(methoxyiminomethyl)-2-methyl benzoic acid amide in 4 mL of methanol and 1 mL of water, 30 mg of hydroxyamine hydrochloride was added at room temperature with stirring, and continued to stir at the same temperature for 1.5 hour. After the completion of the reaction, 10 mL of water was added in the reaction mixture, and extracted with ethyl acetate (10 mL×2). The combined organic phases were dehydrated with and dried over saturated sodium chloride aqueous solution and then anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified with silica gel column chromatography that were eluated with ethyl acetate-hexane (1:1) to obtain 70 mg of the aimed product as white crystal.
