Procedure
A 1N aqueous saturated solution of sodium hydroxide (5 ml) was added to a solution of methyl E-4-[4-[2-(methyl-2-pyrimidylamino)ethoxy]benzyloxyimino]-4-phenylbutyrate (1.22 g) in tetrahydrofuran (10 ml)-methanol (5 ml) and stirred at room temperature for 1 hour. 1N hydrochloric acid (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 E-4-[4-[2-(methyl-2-pyrimidylamino)ethoxy]benzyloxyimino]-4-phenylbutyric acid (1.09 g, yield 92%) as colorless crystals. m.p. 72-73° C.
