4-(Trifluoromethyl)-1-benzenecarbonyl chloride (262 mg, 1.256 mmol) in dichloromathane (1 mL) was added to a solution of trans-3-(4-amino-3-methoxyphenyl)-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (500 mg, 1.145 mmol) in pyridine (8 mL) at 0° C. After 30 minutes, the ice bath was removed the the reaction mixture was stirred at room temperature for 1.5 hour. Solvent was evaporated and the residue was purified by flash column chromatography using dichloromethane/methanol (80:20) as mobile phase to give trans-N1-(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-2-methoxyphenyl)-4-(trifluoromethyl)benzamide (516 mg, 74%). 1H NMR (CDCl3-d) δ 1.55 (m, 2H), 1.74 (m, 2H), 2.10-2.27 (m, 6H), 2.30 (s, 3H), 2.51 (m, 4H), 2.66 (m, 3H), 3.96 (s, 3H), 4.04 (s, 3H), 4.78 (m, 1H), 5.57 (bs, 2H), 7.30 (m, 2H), 7.79 (d, J=8.25 Hz, 2H), 8.04 (d, J=8.05 Hz, 2H), 8.38 (s, 1H), 8.64 (s, 1H), 8.68 (d, J=8.20 Hz, 1H).
