실험 절차

To a stirred solution of 2-(5-fluoro-2-methyl-3-(2-(piperidin-1-ylsulfonyl)benzyl)-1H-indol-1-yl)acetic acid ethyl ester (1.23 g, 2.60 mmol) in THF (50 mL), was added a solution of potassium hydroxide (0.73 g, 13.0 mmol) in water (50 mL), and the resulting solution stirred at room temperature for 2 hours. Aqueous HCl (2N, 15 mL) was then added and the aqueous layer extracted with ethyl acetate (100 mL). The organic layers were washed with brine (2×50 mL), dried over anhydrous magnesium sulfate, filtered and evaporated in vacuo. The solid was triturated with diethyl ether and dried in vacuo to afford 2-(5-fluoro-2-methyl-3-(2-(piperidin-1-ylsulfonyl)benzyl)-1H-indol-1-yl)acetic acid (1.09 g, 2.45 mmol, 94%).
