Procedure
To a solution of ethyl 3-[4-({4-[(3,5-diphenyl-1H-pyrazol-1-yl)methyl]-3-methoxybenzyl}amino)-2-fluorophenyl]propanoate (0.57 g, 1.01 mmol) in a mixture of methanol (4.0 mL) and tetrahydrofuran (8.0 mL) was added 1 N aqueous sodium hydroxide solution (2.02 mL, 2.02 mmol), and the mixture was stirred at room temperature for 3 hr. The reaction mixture was diluted with ethyl acetate, and the organic layer was washed with 10% aqueous citric acid solution and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=2/1-hexane/ethyl acetate=1/2) to give a colorless oil. The obtained oil was dissolved in ethyl acetate, and 4 N hydrogen chloride/ethyl acetate solution was added. The precipitated crystals were collected by filtration, washed with ethyl acetate and dried to give the title compound (0.48 g, yield 77%) as colorless crystals.
