Reaction Steps

3-(1-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl)-4-(5-(piperidin-1-ylmethyl)thiophen-2-yl)-1H-isochromen-1-one hydrochloride (Intermediate D9, 100 mg, 0.154 mmol), 3-fluoro-5-hydroxyphenylboronic acid (48.1 mg, 0.308 mmol), S-Phos-Pd-G2 (11.10 mg, 0.015 mmol) and K3PO4 (151 mg, 0.462 mmol) were reacted in THF (1.2 ml) and water (0.3 ml) under argon at 80° C. under mw irradiation for 30 min The reaction was quenched by the addition of 1M HClaqueous (2 ml) and the mixture purified via reverse phase chromatography using a Biotage C18 60 g SNAP with a gradient of water and acetonitrile to give (prior to drying a small amount of 1M HCl aqueous was added) the title compound (70 mg, 71.7% yield) as yellowish solid.
