実験手順

To a solution of ethyl 3-(2-fluoro-4-{[4-({5-(2-phenylethyl)-3-[4-(trifluoromethyl)phenyl]-1H-pyrazol-1-yl}methyl)benzyl]amino}phenyl)propanoate in ethanol (10 mL) and tetrahydrofuran (10 mL) was added 1 M aqueous sodium hydroxide solution (4 mL), and the mixture was stirred at room temperature for 2 hr. The reaction mixture was poured into water, and the mixture was weakly acidified with 10% aqueous citric acid solution and extracted with ethyl acetate. The ethyl acetate layer was dried using a Presep Dehydration tube (manufactured by Wako Pure Chemical Industries, Ltd.), and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (20%-80% ethyl acetate/hexane) to give the title compound (620 mg, yield 51%, 2 steps) as a yellow oil.
