Reaction Steps

To a solution of 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (1.0770 g, 4.12 mmoles) in DMF (10 ml), ethanol (5 ml) and water (5 ml), 2-chloro-5-methoxyphenyl boronic acid (1.00 g, 5.364 mmoles) and sodium carbonate (2.186 g, 20.63 mmoles) were added and the system is degassed for 30 min Tetrakis triphenylphosphine Palladium (0.905 g, 0.783 mmoles) was added under nitrogen atmosphere and heated to 80° C. After 12 h, the reaction mixture was celite filtered, concentrated and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography with methanol:dichloromethane to afford the title compound as green solid (0.090 g, 16% yield). 1H-NMR (δ ppm, DMSO-d6, 400 MHz): δ 13.61(s, 1H), 8.19(s, 1H), 7.51(d, J=8.9Hz, 1H), 7.09(d, J=8.9Hz 1H), 7.06(d, J=2.6Hz 1H), 3.78(s,3H).
