Procedure

A mixture of 4-(chloromethyl)-5-methyl-2-phenylthiazol (394 mg), methy E-4-(4-hydroxybenzyloxyimino)-4-phenylbutyrate (500 mg), potassium carbonate (442 mg) and N,N-dimethyformamide (10 ml) was stirred at room temperature for 72 hours. Water was added to the reaction mixture and extracted with ethyl acetate. The ethyl acetate layer was subjected to silica gel chromatography to obtain methy E-4-[4-(5-methyl-2-phenyl-4-thiazolylmethoxy)benzyloxyimino]-4-phenylbutyrate (570 mg, yield 71%) as a colorless oil from an ethyl acetate-hexane (1:5, v/v)-eluted fraction.
