Procedure

A warmed solution of 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 (0.072 g, 0.12 mmol) in ethyl acetate (20 mL) was treated with methane sulfonic acid (0.012 g, 0.12 mmol). A precipitate slowly formed and was filtered under a nitrogen atmosphere to give 0.051 g of 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 di-mesylate. The melting range was determined to be 345.5 to 348.1° C. 1H NMR (d6-DMSO) δ 9.4353 (s, 1H), 8.2461 (s, 1H), 8.1239-8.1035 (d, 1H, J=8.16 Hz), 7.7182-7.6985 (d, 1H, J=7.88 Hz), 7.6004-7.5792 (d, 1H, J=8.48 Hz), 7.3442-7.2794 (m, 4H), 7.1718-7.1349 (t, 1H), 4.6829 (m, 1H), 4.0396 (s, 3H), 3.9570 (s, 3H), 2.6703 (m, 6H), 2.5 (s, 3H), 2.2949 (s, 6H), 2.0891-2.9086 (m, 7H), 1.5179 (m, 2H).
