2,2-Dimethyl-3-phenylpropanoyl chloride (52 mg, 0.264 mmol) was added to a solution of trans-3-(4-amino-2-fluoro-5-methoxyphenyl)-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-4-amine (80 mg, 0.176 mmol) in pyridine (1.5 mL). After 5 hours, the solvent was evaporated and the residue was first purified by flash column chromatography chromatography using dichloromethane/methanol (95:5 to 85:15) as mobile phase then by preparatory LC/MS to give trans-N1-(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-5-fluoro-2-methoxyphenyl)-2,2-dimethyl-3-phenylpropanamide (22 mg, 19%). 1H NMR (CDCl3-d) δ 1.33 (s, 6H), 1.57 (m, 2H), 1.92 (m, 2H), 2.15 (m, 6H), 2.30 (s, 3H), 2.49 (m, 4H), 2.66 (m, 3H), 2.95 (s, 2H), 3.84 (s, 3H), 4.76 (m, 1H), 5.51 (bs, 2H), 6.98 (d, J=6.86 Hz, 1H), 7.15 (m, 2H), 7.23 (m, 3H), 8.01 (s, 1H), 8.35 (s, 1H), 8.47 (d, J=11.88, 1H).
