実験手順

4-(Trifluoromethyl)-1-benzenecarbonyl chloride (35 mg, 0.170 mmol) in dichloromethane (0.3 mL) was added to a solution of 3-(4-amino-3-methoxyphenyl)-1-(1-methyl-4-piperidyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (60 mg, 0.17 mmol) in pyridine (1.2 mL) at 0° C. After 5 minutes, the ice-water bath was removed and the reaction mixture was stirred at room temperature for 1 hours then, more 4-(trifluoromethyl)-1-benzenecarbonyl chloride (18 mg, 0.086 mmol) was added. 2 hours later, the solvent was evaporated and the residue was purified by flash column chromatography using dichloromethane/methanol (95:5 to 70:30) as mobile phase to give N1-{4-[4-amino-1-(1-methyl-4-piperidyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-4-(trifluoromethyl)benzamide (85 mg, 95%). 1H NMR (CDCl3) δ 2.10 (m, 2H), 2.37-2.59 (m, 7H), 3.15 (m, 2H), 4.02 (s, 3H), 4.83 (m, 1H), 5.68 (s, 2H), 7.34 (m, 2H), 7.80 (d, J=8.21 Hz, 2H), 8.04 (d, J=8.10 Hz, 2H), 8.38 (s, 1H), 8.67 (m, 2H).
