Procedure

2-amino-5-bromonicotinaldehyde (0.1 g, 0.5 mmol), 3-cyanophenylboronic acid (0.146 g, 1.0 mmol), dichlorobis(triphenylphosphine)palladium(II) (0.017 g, 0.02 mmol), and K2CO3 (0.14 g, 1.0 mmol) were combined in 3 mL of 4:1 CH3CN:H2O and heated to 150° C. for 5 minutes in the SmithSynthesizer™ microwave instrument. Upon cooling, the reaction mixture was chromatographed on silica gel eluting with hexanes/ethyl acetate (0% EtOAc to 100% EtOAc over 10 minutes) to afford 3-(6-amino-5-formylpyridin-3-yl)benzonitrile (46 mg) as a solid.
