4-(Trifluoromethyl)benzoyl chloride → N1-{4-[4-amino-1-(1-methyl-4-piperidyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-4-(trifluoromethyl)benzamide

Reaction Steps

4-(Trifluoromethyl)-1-benzenecarbonyl chloride (48 mg, 0.231 mmol) was added to a solution of 3-(4-amino-3-methoxyphenyl)-1-[1-(1-methylpiperidin-4-yl)-piperidin-4-yl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (101 mg, 0.231 mmol) in pyridine (1.0 mL). After 5 hours, the solvent was evaporated and the residue was purified by flash column chromatography to give N1-{4-[4-amino-1-(1-methyl-4-piperidyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-4-(trifluoromethyl)benzamide (83 mg, 59%). 1H NMR (CDCl3-d) δ 1.68 (m, 2H), 1.82 (m, 4H), 2.01 (m, 4H), 2.29 (s, 3H), 2.44 (m, 3H), 2.93 (m, 2H), 3.30 (m, 2H), 4.03 (s, 3H), 4.77 (m, 1H), 5.60 s, 2H), 7.33 (m, 2H), 1.79 d, J=8.19 Hz, 2H), 8.04 (d, J=8.04 Hz, 2H), 8.37 (s, 1H), 8.66 (m, 2H).
