実験手順
To a solution of 4-[3-cyclohexylethynyl-6-(4-hydroxy-phenyl)-1-(tetrahydro-pyran-2-yl)-1H-pyrazolo[3,4-b]pyridine-4-carbonyl]-piperazine-1-carboxylic acid tert-butyl ester (0.34 g, 0.56 mmol) in methanol (15 ml) was added Pd/C (10%, 12 mg, 0.01 mmol). The reaction mixture was hydrogenated at 4 bar for 18 h, Pd/C (10%, 12 mg, 0.01 mmol) was added and hydrogenation pursued for an additional 8 hours. The reaction mixture was then filtered and concentrated under reduced pressure to yield the title compound (0.33 g, 95%) as a grey solid.
