Reaction Steps
Lithium hydroxide hydrate (38 mg; 0.90 mmole) dissolved in water (2 ml) was added to a solution of 3-{4-[2-(4-dimethylaminophenyl)ethoxy]phenyl}-2-ethoxypropanoic acid ethyl ester (described in Example 99) (232 mg; 0.60 mmole) in tetrahydrofuran (6 ml). The reaction mixture was stirred at room temperature for 3 hours. The reaction mixture was acidified with hydrochloric acid (2 M) to pH 5. Tetrahydrofuran was evaporated in vacuo, water (5 ml) was added and the mixture was extracted with ethyl acetate (10+5 ml), dried (sodium sulfate) and the solvent was evaporated in vacuo. Purification by filtration on silica gel gave 180 mg (yield 84%) of 3-{4-[2-(4-dimethylaminophenyl)ethoxy]phenyl}-2-ethoxypropanoic acid.
