Procedure
To a solution of ethyl (3R)-1-[(7-{[3-(trifluoromethyl)-4-{[(2S)-1,1,1-trifluoropropan-2-yl]oxy}benzyl]oxy}-2H-chromen-3-yl)methyl]piperidine-3-carboxylate (271 mg) in EtOH (5.4 mL)-THF (2.7 mL) was added a 1 M aqueous NaOH solution (923 μL), followed by stirring at 50° C. for 2 hours. The reaction liquid was cooled to room temperature, then 1 M hydrochloric acid (923 μL) was added thereto, and the vehicle was evaporated. The residue was purified by reverse phase chromatography (H2O:MeCN=100:0 to 30:70) to obtain a yellow oily substance, which was dissolved in dioxane (3 mL), treated with 4 N HCl/dioxane (1 mL), and washed with IPE to obtain (3R)-1-[(7-{[3-(trifluoromethyl)-4-{[(2S)-1,1,1-trifluoropropan-2-yl]oxy}benzyl]oxy}-2H-chromen-3-yl)methyl]piperidine-3-carboxylic acid hydrochloride (215 mg) as a white powder.
