実験手順
A 1 M solution of tetrabutylammonium fluoride in tetrahydrofuran (0.105 mL, 0.105 mmol) was added to (4′-{1-ethyl-1-[3-methyl-4-(1-trimethylsilanyloxy-cyclopentylethynyl)-phenyl]-propyl}-3-fluoro-2′-methyl-biphenyl-4-yl)acetic acid methyl ester (Example 93-(1); 52.6 mg, 0.0878 mmol), and the mixture was stirred for 40 minutes. A saturated aqueous ammonium chloride solution was added to the reaction mixture, followed by extraction with diethyl ether. The organic layer was washed with water, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (20% ethyl acetate/hexane) to give the title compound (41.1 mg, 88%).
