実験手順

To a solution of 4-[6-(4-hydroxy-phenyl)-1-(tetrahydro-pyran-2-yl)-3-vinyl-1H-pyrazolo[3,4-b]pyridine-4-carbonyl]-piperazine-1-carboxylic acid tert-butyl ester (0.30 g, 0.56 mmol) in DMF (2.55 mL) were added 1-(3-iodo-phenyl)-pyrrolidin-2-one (0.19 g, 0.67 mmol), tri(o-tolyl)phosphine (34 mg, 0.11 mmol) and triethylamine (2.55 mL). The resulting solution was degassed using argon, palladium acetate (6 mg, 0.03 mmol) was then added and the reaction mixture was heated at 125° C. overnight. The reaction mixture was concentrated under vacuum and the residue taken up in water and then acidified to pH=1. The precipitate was filtered, washed with water and then dried under vacuum. The crude residue was purified by silica gel column chromatography using a gradient of EtOAc (0-100%) in cyclohexane to yield the title compound as a beige solid (0.26 g, 66%).
