Reaction Steps

Boronate-2-methyl-2-[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]propanenitrile (200 mg, 0.7376 mmol), iodide-4-iodo-5-methyl-1H-pyrazolo[3,4-b]pyridine (191.1 mg, 0.7376 mmol), Na2CO3 (1.106 mL of 2 M, 2.213 mmol) and Pd(PPh3)4 (85.23 mg, 0.07376 mmol) were placed in a microwave tube and dry Dioxane (5.000 mL) was added. The resulting suspension was stirred at 150° C. in the microwave (using a 10 minute ramp and nitrogen cooling) for 60 minutes. The reaction mixture was partitioned between EtOAc and brine. The aqueous layer was extracted with EtOAc (3×20 mL) and the combined organics were dried over Na2SO4, filtered and concentrated under reduced pressure to give an oil. The mixture was purified by column chromatography (10-100% EtOAc in hexanes, ˜100 mL silica, loaded in DCM) to give an oil which was lyophilised from MeCN/H2O to give a solid (217 mg, 57% Yield).
