Procedure

A mixture of {5-fluoro-2-methyl-3-[3-(pyridine-4-sulfonyl)thiophen-2-ylmethyl]indol-1-yl}acetic acid methyl ester (0.026 g) and tetrahydrofuran (0.5 mL) was treated with 2.0 M aqueous sodium hydroxide solution (2.0 mL), and the resulting mixture was stirred at room temperature for 3 hours. The mixture was acidified by the addition of 2.0 M aqueous hydrochloric acid solution and concentrated under reduced pressure. The residue was purified by preparative HPLC, eluting with a mixture of acetonitrile and water (1:19 to 1:1 by volume) to afford the title compound as yellow solid (0.015 g).
