Procedure
trans-3-Iodo-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (200 mg, 0.453 mmol), 1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl]-1H-benzo[d]imidazole (303 mg, 0.906 mmol), palladium tetrakistriphenyphosphine (0.31 mg, 0.027 mmol) and sodium carbonate (155 mg, 1.09 mmol) were mixed with ethylene glycol dimethyl ether (5 mL) and water (2.5 mL). The reaction mixture was heated at reflux overnight under nitrogen. The solvent was removed and the residue was purified by reverse phase preparative HPLC (Rainin HPLC, Column: Thermoquest, hyperprep HS C18, 8 um, 250×21.2 mm. Eluents: 5% B/A to 100% B/A in 25 min. (B: acetonitrile, A: 50 mM ammonia acetate buffer, pH 4.5), 21 mL/min.) to give trans-3-[4-(1H-benzo[d]imidazol-1-ylmethyl)-3-methoxyphenyl]-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (35 mg, 15%). 1H NMR (DMSO-d6) δ 1.46 (m, 2H), 1.95 (m, 10H), 2.13 (s, (3H), 2.32 (m, 5H), 4.62 (m, 1H), 5.78 (s, 2H), 7.22 (m, 2H), 7.49 (m, 2H), 7.62 (m, 4H), 8.22 (s, 1H), 8.44 (s, 1H). LCMS (Thermoquest AQA single Quad MS, Finnigan HPLC-Column: Genesis, C18, 3 um, 33×4.6 mm. Eluents: 30% B/A to 95% B/A in 4.5 min. (B: acetonitrile, A: 50 mM ammonia acetate buffer, pH 4.5), 0.8 mL/min.): MH+=522.3, Rt=0.82 min.
