実験手順

In a reaction flask, 4-(4-{3-[2,6-difluoro-3-(propane-1-sulfonylamino)-benzoyl]-1H-pyrrolo[2,3-b]pyridin-5-yl}-pyrazol-1-yl)-piperidine-1-carboxylic acid tert-butyl ester (P-1001, 42.0 mg, 0.067 mmol) is dissolved in 9.0 mL of dichloromethane and 1.0 mL of trifluoroacetic acid and the reaction is stirred at room temperature for 2 hours. Aqueous saturated sodium bicarbonate is added and the mixture is extracted with ethyl acetate. The aqueous layer is frozen and lyophilized and the residue is suspended in tetrahydrofuran and sonicated. The mixture is filtered twice and the filtrate is concentrated under vacuum. The resulting material is purified by reverse phase HPLC, eluting with acetonitrile/water with 0.1% formic acid, 5-47.5% acetonitrile over 40 minutes. Appropriate fractions are combined and dried by lyophilization to provide the desired compound as a white solid (P-1002, 5.7 mg). MS (ESI) [M+H+]+=529.0.
