실험 절차

After a mixture of 4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyamine (600 mg), methyl 8-(4-methoxyphenyl)-8-oxooctanoate (538 mg), acetic acid (0.331 ml), sodium acetate (317 mg) and methanol (20 ml) was heated to reflux for 16 hours, the mixture was cooled to room temperature. Water was added to the reaction mixture and extracted with ethyl acetate. The ethyl acetate layer was washed with an aqueous saturated solution of sodium chloride, dried (MgSO4) and concentrated. The residue was subjected to silica gel chromatography to obtain methyl E-8-(4-methoxyphenyl)-8-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]octanoate (650 mg, yield 59%) as a colorless oil from an ethyl acetate-hexane (2:7, v/v)-eluted fraction.
