Procedure
To 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) (0.200 g, 0.373 mmol), triethylamine (0.052 mL, 0.37 mmol), and sodium iodide (0.056 g, 0.37 mmol) in DMF (5 mL) was added morpholine (0.039 mL, 0.45 mmol). The reaction mixture was heated at 60° C. for 60 h. Morpholine (0.100 mL, 1.15 mmol) was added and the reaction mixture was heated at 80° C. for 30 h. The reaction mixture was cooled to ambient temperature and concentrated in vacuo. Water (5 mL) was added and the resulting precipitate was collected by filtration, washed with water (5 mL) and ether (10 mL), and dried in vacuo to afford a tan solid which was purified twice by silica gel chromatography (elution with 20% MeOH—CH2Cl2); the appropriate fractions were combined and concentrated to afford a beige solid which was triturated from ether 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 as a white solid (0.048 g, 0.054 mmol): 1H NMR (d6-DMSO, 400 MHz): δH 9.44 (1H, s), 8.26 (1H, s), 8.11 (1H, d, J=8.0 Hz), 7.70 (1H, d, J=7.6 Hz), 7.58 (1H, d, J=7.6 Hz), 7.29-7.35 (4H, m), 7.15 (1H, t, J=7.6 Hz), 4.48 (2H, t, J=6.4 Hz), 4.04 (3H, s), 3.96 (3H, s), 3.50-3.53 (4H, m), 2.82 (2H, t, J=6.2 Hz), and 2.47-2.51 (4H, 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 10.02 min. MS: M+ 527.3.
