Reaction Steps

To a solution of 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.700 g, 2.68 mmoles) in DMF (10 ml), ethanol (5 ml) and water (5 ml), 3-Fluoro-5-methoxyphenyl boronic acid (0.592 g, 3.48 mmoles) and sodium carbonate (1.42 g, 13.40 mmoles) were added and the system is degassed for 30 min. Palladium tetrakis triphenylphosphine (0.588 g, 0.509 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 yellow solid (0.260 g, 37% yield). 1H-NMR (δ ppm, DMSO-d6, 400 MHz): δ 13.64 (s, 1H), 8.21 (s, 1H), 7.03 (m, 2H), 6.93 (td, J=11.1, 2.3 Hz, 1H), 3.83 (s, 3H).
