Participants

Reaction Steps

N-{4-[(1R,3S)-3-{[(1R)-1-(Naphthalen-1-yl)ethyl]amino}cyclopentyl]benzoyl}glycine ethyl ester (139 mg, 0.31 mmol) was dissolved in ethanol (2 mL), followed by addition of 1N aqueous sodium hydroxide (2 mL), and the mixture was stirred for 4 hours at room temperature. 1N hydrochloric acid was added dropwise to the reaction mixture to make the reaction solution acidic, and the solvent was distilled off under reduced pressure. Diisopropyl ether and water were added to the reaction mixture, followed by ultrasonic wave treatment, and then the solid generated was collected by filtration to give the title compound (52 mg, 37%).
