To [6-(6-cyclopropyl-pyridin-3-ylamino)-2-fluoro-pyridin-3-yl]-(5-methyl-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-methanone (74, 134 mg, 0.25 mmol) in 10 mL of tetrahydrofuran, tetrabutylammonium fluoride, trihydrate (85.53 mg, 0.27 mmol) is added and the reaction stirred at room temperature for 30 minutes. Water is added and the mixture is extracted with ethyl acetate. The organic layer is washed with water and brine, dried with magnesium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material is purified by silica gel column chromatography, eluting with ethyl acetate in hexane. Appropriate fractions are combined and concentrated under vacuum to provide the desired compound (P-3051, 82 mg). MS (ESI) [M+H+]+=388.0.
