실험 절차

3-[4-{2-(4-[Benzyloxycarbonylamino]phenyl)ethoxy}phenyl]-(S)-2-ethoxypropanoic acid ethyl ester (described in Example 52) (0.16 g; 0.32 mmole) was dissolved in tetrahydrofuran and lithium hydroxide (9 mg; 0.38 mmole) dissolved in water (1 ml) was added. The resulting mixture was stirred over night. Hydrochloric acid (1M; 1 ml) was added. Tetrahydrofuran was evaporated and the remaining water residue was extracted three times with ethyl acetate. The organic phase was dried with magnesium sulfate and evaporated to give 0.14 g (92.8% yield) of 3-[4-{2-(4-[benzyloxycarbonylamino]-phenyl)ethoxy}phenyl]-(S)-2-ethoxypropanoic acid.
