Reaction Steps

A solution of 2-fluoro-4-trifluoromethyl-1-benzenecarbonyl chloride (0.87 g, 3.83 mmol) in dichloromethane (5 mL) was added into a mixture of pyridine (15 mL) and 4-[4-amino-3-(4-amino-3-methoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-cyclohexanone (1.00 g, 2.56 mmol) in dichloromethane (5 mL) at 0° C. over 5 minutes. The mixture was stirred at 0° C. for 10 minutes and at ambient temperature overnight. The solvent was removed under reduced pressure. The residue was partitioned between water and dichloromethane. The dichloromethane layer was washed with saturated aqueous ammonium chloride twice and saturated aqueous sodium chloride solution, dried over magnesium sulfate, filtered and evaporated under reduced pressure to give a crude product. The crude product was purified by flash column chromatography on silica using Isco system to provide N1-{4-[4-amino-1-(4-oxocyclohexyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-2-fluoro-4-trifluoromethylbenzamide (0.95 g, 1.76 mmol) as a white solid: 1H NMR (DMSO-d6, 400 MHz) δ 9.90 (dd, 1H), 8.30(d, 1H), 8.28 (s, 1H), 7.99 (t, 1H), 7.89 (d, 1H), 7.75 (d, 1H), 7.34 (s, 1H), 7.30 (d, 1H), 6.90 (br, 2H), 5.27 (m, 1H), 3.94 (s, 3H), 2.70 (m, 2H), 2.47 (m, 4H), 2.17 (m, 2H); RP-HPLC (Hitachi HPLC, Hypersil C18, 5 μm, 100 Å, 250×4.6 mm; 25%-100% acetonitrile-0.05M ammonium acetate over 10 min, 1 mL/min) Rt 9.23 min. MS: MH+ 543.
