Versuchsvorschrift
Benzyl (R)-2-[3-[N-(benzoxazol-2-yl)-N-(3-(4-methoxyphenoxy)propyl)aminomethyl]phenoxy]butyrate (72 mg) was dissolved in ethanol (3 mL), and a 4 N aqueous sodium hydroxide solution (0.5 mL) was added at 0° C. Then, the resulting mixture was stirred at room temperature for 1 hour. The reaction liquor was concentrated under reduced pressure, and then was dissolved in chloroform (30 mL). The solution was washed with a saturated aqueous solution of ammonium chloride and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure, and the residue was purified by preparative TLC (chloroform/methanol=10/1) to obtain a colorless solid (61 mg, 100%).
