A mixture of 4-cyano-3-fluorophenylboronic acid (0.495 g, 3 mmol), 5-bromonicotinaldehyde (0.558 g, 3.00 mmol), sodium carbonate (2M in water, 3.00 mL, 6.00 mmol), bis(triphenylphosphine)palladium(II) chloride (0.053 g, 0.075 mmol) in DMF (10 mL) was heated to 95° C. for 3 h. After concentration, the residue was dissolved into CH2Cl2-MeOH and mixed with silica gel and concentrated. After flash column (MeOH—CH2Cl2, v/v, 0.5%-1%) yielded a colorless solid (170 mg) ESI-MS m/z: 227 [M+1]+.
