Reaction Steps

A 1N aqueous saturated solution of sodium hydroxide (5 ml) was added to a solution of ethyl E-2-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]-2-(3-pyridyl)acetate (520 mg) in tetrahydrofuran (10 ml)-methanol (5 ml) and stirred at 40° C. for 1 hour. 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 acetone-diisopropyl ether to obtain E-2-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]-2-(3-pyridyl)acetic acid (427 mg, yield 88%) as colorless crystals. m.p. 130-131° C.
