Reaction Steps

A 1N aqueous saturated solution of sodium hydroxide (5 ml) was added to a solution of ethyl Z-2-(3-bromophenyl)-2-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]acetate (430 mg) in tetrahydrofuran (10 ml)-methanol (5 ml) and stirred at 40° C. for 2 hours. 1N hydrochloric acid (5.5 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 residue was recrystallized from ethyl acetate-hexane to obtain Z-2-(3-bromophenyl)-2-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]acetic acid (370 mg, yield 91%) as colorless crystals. m.p. 181-182° C.
