Versuchsvorschrift

trans-3-Iodo-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (266 mg, 0.604 mmol), 4-(anilinocarbonyl)-3-methoxyphenylboronic acid (180 mg, 0.664 mmol), palladium tetrakistriphenyphosphine (42 mg, 0.036 mmol) and sodium carbonate (154 mg, 1.449 mmol) were mixed with ethylene glycol dimethyl ether (8 mL) and water (4 mL). The reaction mixture was heated at reflux overnight. Organic solvent was removed under reduced pressure and the aqueous layer was extracted with dichloromethane. The combined organic layer was washed with water then brine, dried over MgSO4, filtered and evaporated. The residue was purified by flash column chromatography using dichloromethane/methanol (95:5) as mobile phase to give trans-N1-phenyl-4-{4-amino-1-[-4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-2-methoxybenzamide (226 mg, 69%). 1H NMR (CDCl3) δ 1.58 (m, 4H), 2.17 (m, 7H), 2.32 (s, 3H), 2.52 (m, 2H), 2.69 (2.69, 3H), 4.16 (s, 3H), 4.78 (m, 1H), 5.49 (bs, 2H), 7.14 (m, 1H), 7.43 (m, 4H), 7.69 (m, 2H), 8.44 (m, 2H), 9.77 (s, 1H).
