Reaction Steps

After a mixture of 4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyamine (500 mg), ethyl 4-oxo-4-(3-pyridyl)butyrate (367 mg), acetic acid (0.276 ml), sodium acetate (264 mg) and ethanol (20 ml) was heated to reflux for 20 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 ethyl 4-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]-4-(3-pyridyl)butyrate (590 mg, yield 73%) as a colorless oil from an ethyl acetate-hexane (3:2, v/v)-eluted fraction.
