Versuchsvorschrift

To a mixture of N2-{4-[4-amino-1-(2-morpholinoethyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-1-methyl-1H-2-indolecarboxamide (0.048 g, 0.091 mmol) in warm ethyl acetate (2 mL) was added a solution of maleic acid (0.021 g, 0.18 mmol) in warm ethyl acetate (1 mL). A precipitate formed immediately. The reaction mixture was allowed to cool to ambient temperature and the precipitate was collected by filtration, washed with ethyl acetate (5 mL), and dried in vacuo to afford N2-{4-[4-amino-1-(2-morpholinoethyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-1-methyl-1H-2-indolecarboxamide dimaleate as a light brown solid (0.030 g, 0.039 mmol): 1H NMR (d6-DMSO, 400 MHz): δH 9.45 (1H, s), 8.31 (1H, s), 8.15 (1H, d, J=8.0 Hz), 7.71 (1H, d, J=8.0 Hz), 7.59 (1H, d, J=8.4 Hz), 7.31-7.35 (4H, m), 7.16 (1H, t, J=7.4 Hz), 6.17 (4H, s), 4.72-4.73 (2H, m), 4.04 (3H, s), 3.96 (3H, s), 3.72-3.79 (4H, m), and 3.10-3.30 (6H, obscured by water peak); RP-HPLC (Hypersil C18, 5 μm 100 Å, 15 cm; 5%-100% acetonitrile-0.1 M ammonium acetate over 15 min, 1 mL/min). Rt 11.08 min. MS: M+527.3.
