Procedure

To [2,4-Difluoro-3-(5-pyridin-3-yl-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-phenoxy]-acetic acid methyl ester (550, 40.0 mg, 0.071 mmol, prepared as described in Example 65, Scheme 46) in tetrahydrofuran (5.0 mL) was added tetra-n-butylammonium fluoride (22.2 mg, 0.085 mmol). The reaction was stirred at room temperature for 10 minutes. The crude compound was concentrated with silica gel and purified by silica gel column chromatography eluting with 3% methanol in methylene chloride to give the compound as white solid (P-1465, 20 mg, 69%). MS (ESI) [M+H+]+=410.2.
