Reaction Steps

A mixture of 5-chloromethyl-3-phenyl-1,2,4-oxadiazole (362 mg), ethyl E-6-(4-hydroxybenzyloxyimino)-6-phenylhexanoate (600 mg), potassium carbonate (467 mg) and N,N-dimethylformamide (7 ml) was stirred at room temperature for 18 hours. 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 E-6-phenyl-6-[4-(3-phenyl-1,2,4-oxadiazol-5-ylmethoxy)benzyloxyimino]hexanoate (789 mg, yield 92%) as a colorless oil from an ethyl acetate-hexane (2:9, v/v)-eluted fraction.
