Procedure

To 3-[2,6-difluoro-3-(propane-1-sulfonylamino)-benzoyl]-1H-pyrrolo[2,3-b]pyridine-5-carboxylic acid methyl ester (P-1552, 80.0 mg, 0.18 mmol) in tetrahydrofuran (10.0 mL) were added water (3.0 mL) and lithium hydroxide (82 mg, 3.4 mmol). The reaction was stirred at room temperature overnight. The reaction was poured into water, acidified with 1 N HCl to pH around 1, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, filtered, concentrated, and washed with ethyl acetate to give an off-white solid (P-1559, 60 mg, 77%) MS (ESI) [M+H+]+=424.2.
