Procedure

Lithium hydroxide monohydrate (54.8 mg) was added to a solution of methyl E-4-phenyl-4-[4-(2-phenyl-4-thiazolylmethoxy)benzyloxyimino]butyrate (424 mg) in tetrahydrofuran (10 ml)-water (4 ml)-metbanol (4 ml) and stirred at room temperature for 2 hours. 1N hydrochloric acid (1.4 ml) 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 remaining crystals were recrystallized from ethyl acetate-hexane to obtain E-4-phenyl-4-[4-(2-phenyl-4-thiazolylmethoxy)benzyloxyimino]butyric acid (369 mg, yield 90%) as colorless crystals. m.p. 104-105° C.
