Procedure

To [2,4-Difluoro-3-(5-pyridin-3-yl-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-phenoxy]-acetic acid methyl ester (P-1465, 20.0 mg, 0.049 mmol) in tetrahydrofuran (8.0 mL) were added potassium hydroxide (100.0 mg, 1.8 mmol) and water (3.0 mL). The reaction was stirred at room temperature overnight and then poured into water, acidified to pH=5 with 1 N HCl, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 10% methanol in methylene chloride to give the compound as light yellow solid (P-1468, 9.1 mg, 47%). MS (ESI) [M+H+]+=396.2.
