Procedure
A solution of 50 mg of 2-(1-(iminomethyl)piperidin-4-yl)ethyl (2R)-2-((1R)-3,3-difluorocyclopentyl)-2-hydroxy-2-phenylethanoate monohydrochloride in 2 ml of ultrapure water was developed on reversed phase medium pressure liquid chromatography [ODS-AQ 120-S50 (YMC Co.)], and 60 ml of 0.2 M aqueous sodium bromide solution was flowed. After washing with 100 ml of ultrapure water, the title compound was eluted from tetrahydrofuran/water=1/5, and 35 mg thereof was obtained as a colorless solid upon condensation to dry solid.
