実験手順

1M Aqueous LiOH (0.52 mL) is added at 0° C. to a stirring solution of [1-(3,4-difluoro-benzenesulfonyl)-2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl]-acetic acid methyl ester (200 mg, 0.526 mmol) in 1:1 dioxane/water (4 mL). The reaction mixture is stirred at 0° C. for 15 minutes, then allowed to warm to room temperature. After 2.5 hours, the reaction mixture is neutralised to pH 7 with 1M HCl and the solvent is removed under reduced pressure. The residue is loaded on a pre-packed Isolute™ silica column and eluted using a gradient eluent from 100% CH2Cl2 to 5% methanol in CH2Cl2 to afford [1-(3,4-difluoro-benzenesulfonyl)-2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl]-acetic acid; MH+=367.
