Versuchsvorschrift

To a solution of 1-(2-aminoethyl)-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (287 mg, 0.829 mmole), 2-cyanoacetic acid (85 mg, 1.0 mmole) and TEA (0.14 ml, 1.0 mmole) in DMF (10 mL) was added HATU (347 mg, 0.912 mmole). After stirring 3 hr at room temperature, water was added and extracted with ethyl acetate. The organic layer was washed with aq. NaHCO3 and brine, then dried (Na2SO4), filtered and concentrated. The resulting residue was subjected to column chromatography (3% MeOH/DCM) to provide 90 mg (22% yield from step 1) of N-(2-(4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl)-2-cyanoacetamide.
