Reaction Conditions

Reaction Steps

A suspension of 6-chloro-1H-pyrazolo[3,4-d]pyrimidine (100 mg, 0.65 mmol), benzene boronic acid (1.5 eq), copper acetate (2 eq) and pyridine (2 eq) in dichloromethane (2 mL) was heated in the microwave at 80° C. for 15 min. After cooling to rt, the mixture was filtered and the resulting filtrate concentrated to give 6-chloro-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine as a green oil (138 mg, 92%) which was used without further purification in the next step.
