trans-N2-(4-{4-Amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-2-methoxyphenyl)-1-methyl-1H-2-indolecarboxamide (545 mg, 0.917 mmol) was dissolved in hot ethyl acetate (60 mL) and maleic acid (320 mg, 2.75 mmol) in hot ethyl acetate (5 mL) was added. The reaction mixture was stirred at room temperature for 5 hours. The solid was collected by filtration to trans-N2-(4-{4-amino-1-[4-(4-methylpiperazino)cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-2-methoxyphenyl)-1-methyl-1H-2-indolecarboxamide, dimaleate salt (473 mg). 1H NMR (DMSO-d6) δ 1.60 (m, 2H), 2.06 (m, 6H), 2.68 (s, 3H), 2.83-3.57 (bm, 9H), 3.96 (s, 3H), 4.04 (s, 3H), 4.72 (m, 1H), 6.18 (s, 6H), 7.16 (m, 1H), 7.28-7.36 (m, 4H), 7.59 (d, J=8.44 Hz, 1H), 7.72 (d, J=7.94 Hz, 1H), 8.13 (d, J=8.15, 1H), 8.28 (s, 1H), 9.44 (s, 1H).
