Reaction Steps

A microwave vial (20 ml) was charged with 2-bromo-benzaldehyde (208 mg, 1.0 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrazole (222 mg, 1.2 mmol) and 8 ml of acetonitrile. To this mixture was added 2.4 ml of aqueous sodium carbonate (1M), followed by 50 mg of dichlorobis(triphenylphosphine)-palladium(II). The reaction vessel was sealed and heated at 150° C. for 5 minutes with microwave irradiation. After cooling, the reaction mixture was extracted with ethylacetate. The organic layer was evaporated to provide crude material which was purified by ISCO to give 181 mg of 2-(1-methyl-1H-pyrazol-4-yl)-benzaldehyde (96% yield).
