Procedure

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) (0.080 g, 0.15 mmol), ethanolamine (0.05 mL, 0.82 mmol), triethylamine (0.021 mL, 0.15 mmol), and sodium iodide (0.021 g, 0.15 mmol) in DMF (2.5 mL) was heated at 70° C. for 15 h. The reaction mixture was cooled to ambient temperature and concentrated; water (5 mL) was added and the resulting precipitate was collected by filtration and rinsed with water (5 mL). The crude solid was purified by silica gel column chromatography (elution with 20% MeOH—CH2Cl2). The appropriate fractions were combined and the solvent removed in vacuo to afford N2-[4-(4-amino-1-{2-[(2-hydroxyethyl)amino]ethyl}-1H-pyrazolo[3,4-d]pyrimidin-3-yl)-2-methoxyphenyl]-1-methyl-1H-2-indolecarboxamide as a white solid (0.009 g, 0.02 mmol). RP-HPLC (Hypersil C18, 5 μm, 100 Å, 15 cm; 5%-100% acetonitrile—0.1 M ammonium acetate over 15 min, 1 mL/min). Rt9.39 min. MS: M+501.3.
