Participants

Reaction Steps

{4-[(1R,3S)-3-{[(1R)-1-(Naphthalen-1-yl)ethyl]amino}cyclopentyl]phenoxy}acetic acid ethyl ester (720 mg, 1.7 mmol) was dissolved in ethanol (5 mL), followed by addition of 1N aqueous sodium hydroxide solution (5 mL), and the mixture was stirred for 1 hour at room temperature. 1N hydrochloric acid was added dropwise to the reaction mixture to make the reaction solution acidic, and then the solvent was distilled off under reduced pressure. The aqueous phase was extracted with methylene chloride, the extracted solution was dried over anhydrous magnesium sulfate, and then the solvent was distilled off under reduced pressure. The residue obtained was dissolved in methylene chloride (6 mL), followed by addition of an ethyl acetate solution of 1N hydrochloric acid (2 mL), and then the solvent was distilled off under reduced pressure. Ethyl acetate and hexane were added to the residue, followed by treatment with ultrasonic waves, and then the solid matter generated was collected by filtration to give the title compound (237 mg, 87%).
