Reaction Conditions

Reaction Steps

A microwave tube was charged with 5-bromo-3-methyl-1H-pyrazolo[3,4-b]pyridine (515 mg, 2.43 mmol), dioxane (2 mL), Hermann's catalyst (72.1 mg, 0.12 mmol) and a solution of sodium carbonate (772 mg, 7.29 mmol) in water (5 mL). The mixture was stirred for 20 sec, heated at 165° C. for 15 minutes in a microwave reactor at very high absorption setting. The reaction was vented before handling. The mixture was diluted with EtOAc and stirred for 5 minutes before filtering through diatomaceous earth to provide the title compound (124 mg, 29%).
