Versuchsvorschrift

4,6-Dichloro-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-d]pyrimidine (100 mg, 0.366 mmol), (3-acrylamidophenyl)boronic acid (70 mg, 0.366 mmol) and triphenylphosphine (4 mg, 0.015 mmol) were dissolved in a mixture of toluene (7 mL) and 1 M sodium carbonate (39 mg, 0.367 mmol), after which palladium(II) acetate (2.0 mg, 0.009 mmol) was added and the reaction mixture was stirred for 36 h at 80° C. The reaction was allowed to cool to room temperature, and the solvent was removed in vacuo. The residue was dissolved in ethyl acetate (20 mL) and washed with water (10 mL). The organic layer was separated, the aqueous layer was extracted with ethyl acetate (20 mL), the combined organic layers were washed with brine (20 mL), and dried over Na2SO4 and concentrated. The crude material was purified by flash chromatography (20% ethyl acetate/hexane) to yield the title compound. 1H NMR (400 MHz, CDCl3): δ 8.45 (m, 2H), 7.88 (d, 1H, J=8.0 Hz), 7.85 (d, 1H, J=8.0 Hz), 7.68 (s, 1H), 7.49 (t, 1H, J=8.0 Hz), 6.46 (m, 1H), 6.27 (m, 1H), 6.06 (d, 1H, J=10.4 Hz), 5.79 (d, 1H, J=10.0 Hz), 4.12 (m, 1H), 3.82 (t, 1H, J=10.0 Hz), 2.58 (m, 1H), 2.14 (m, 1H), 1.95 (m, 1H), 1.78 (m, 2H), 1.62 (m, 1H); ESI-MS: 384.10 [M+H]+.
