Procedure

A mixture of 4-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-2-cyclopenten-1-ol (0.12 g, 0.35 mmol), N1-[2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-2-fluoro-4-trifluoromethylbenzamide (0.23 g, 0.53 mmol), tetrakis(triphenyl-phosphine)palladium(0) (0.02 g, 0.02 mmol) and sodium carbonate monohydrate (0.11 g, 0.88 mmol) was heated in a mixture of ethylene glycol dimethyl ether (6 mL) and water (3 mL) at 85° C. for 6 hours under an atmosphere of nitrogen. The mixture was allowed to cool to ambient temperature and solvents were removed under the reduced pressure. The residue was purified by preparative HPLC to yield N1-{4-[4-amino-1-(4-hydroxy-2-cyclopentenyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-2-fluoro-4-trifluoromethylbenzamide (0.18 g, 0.34 mmol) as a white solid: 1H NMR (DMSO-d6, 400 MHz) δ 9.89 (dd, 1H), 8.31(d, 1H), 8.26 (s, 1H), 8.00 (t, 1H), 7.88 (d, 1H), 7.75 (d, 1H), 7.32 (s, 1H), 7.29 (d, 1H), 6.90 (br, 2H), 6.09 (d, 1H), 5.93 (d, 1H), 5.76 (m, 1H), 5.31 (m, 1H), 4.74 (m, 1H), 3.94 (s, 3H), 2.84 (m, 1H), 2.02 (m, 1H); RP-HPLC (Hitachi HPLC, Hypersil C18, 5 μm, 100 A, 250×4.6 mm; 25%-100% acetonitrile-0.05M ammonium acetate over 10 min, 1 mL/min) Rt 8.50 min. MS: MH+ 529.
