The resulting propionic acid derivative (25 mg, 0.053 mmol) was dissolved in a mixture of ethanol (2 mL) and water (1 mL). To the solution was then added lithium hydroxide monohydrate (6 mg). The mixture was stirred for 20 hours at room temperature, and after cooling with ice, cooled with ice, neutralized by addition of diluted hydrochloric acid, and then subjected to extraction using ethyl acetate. The organic layer was collected, washed with water and brine, dried over anhydrous sodium sulfate, and filtered. The ethyl acetate was distilled off under reduced pressure, to give 15 mg of the desired compound as colorless oil residue (yield 63%).
