Lithium Hydroxide → [3-(4-Benzenesulfonylthiazol-5-ylmethyl)-5-fluoro-2-methylindol-1-yl]acetic acid

Participants

Reaction Steps

A mixture of lithium hydroxide (0.10 g), tetrahydrofuran (1.0 mL) and water (1.0 mL) was treated [3-(4-benzenesulfonylthiazol-5-ylmethyl)-5-fluoro-2-methylindol-1-yl]acetic acid methyl ester (0.20 g), and the resulting mixture was stirred at room temperature for 30 minutes. The mixture was diluted with water, concentrated to low bulk under reduced pressure and acidified by the addition of 1.0 M aqueous hydrochloric acid solution. The resulting precipitate was collected by filtration, washed with water and dried to afford the title compound as a white solid (0.19 g).
