Reaction Steps

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), imidazole (0.011 g, 0.15 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. Imidazole (0.011 g, 0.15 mmol) was added and the reaction mixture was heated at 70° C. for 60 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 to afford a beige solid which was taken up in hot ethyl acetate then allowed to slowly cool to ambient temperature. The filtrate was concentrated to afford N2-(4-{4-amino-1-[2-(1H-1-imidazolyl)ethyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}-2-methoxyphenyl)-1-methyl-1H-2-indolecarboxamide (0.034 g, 0.067 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). Rt 10.45 min. MS: M+508.2.
