Reaction Steps

Ethyl E-2-(4-bromophenyl)-2-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]acetate (600 mg) was dissolved in tetrahydrofuran (6 ml)-methanol (3 ml), and 1N aqueous solution of sodium hydroxide (3 ml) was added and the mixture was stirred for 1 hour at 40° C. 1N HCl (3.3 ml) was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride, dried (MgSO4) and then concentrated. The residual crystals were recrystallized from ethyl acetate to obtain E-2-(4-bromophenyl)-2-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]acetic acid (516 mg, yield 99%) as colorless crystals. m.p. 159-160° C.
