Versuchsvorschrift

A mixture of 2-[4-amino-3-(3-methoxy-4-{[(1-methyl-1H-2-indolyl)carbonyl]amino}phenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]ethyl methanesulfonate (Intermediate 4) (0.265 g, 0.495 mmol), N-methylpiperazine (0.065 mL, 0.58 mmol), and triethylamine (0.10 mL, 0.74 mmol) in DMF (5 mL) was heated at 70° C. for 20 h. The reaction mixture was cooled to ambient temperature and the solvent removed in vacuo. Water (25 mL) was added and the resulting precipitate was collected by filtration, washed with water (25 mL) and ether (50 mL), and dried in vacuo to afford a brown solid which was purified by silica gel column chromatography. The appropriate fractions were combined and concentrated to afford N2-(4-{4-amino-1-[2-(4-methylpiperazino)ethyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-2-methoxyphenyl)-1-methyl-1H-2-indolecarboxamide as a beige solid (0.084 g, 0.16 mmol): 1H NMR (d6-DMSO, 400 MHz): δH 9.44 (1H, s), 8.26 (1H, s), 8.11 (1H, d, J=8.4 Hz), 7.70 (1H, d, J=8.4 Hz), 7.29-7.35 (4H, m), 7.15 (1H, t, J=7.4 Hz), 4.46 (2H, t, J=6.8 Hz), 4.04 (3H, s), 3.96 (3H, s), 2.80 (2H, t, J=6.6 Hz), 2.49-2.50 (2H, obscured by DMSO peak), 2.23-2.26 (4H, m), 2.12 (3H, s), and 0.97-0.99 (2H, m); 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 10.24. MS: MH+ 540.3.
