Procedure
2-(1H-1,2,4-Triazol-3-yl)pyridine (0.24 g, 1.6 mmol), potassium carbonate (0.45 g, 3.2 mmol) and 3-fluorobenzonitrile (0.20 g, 1.6 mmol) were stirred in DMF (20 mL) at ambient temperature. The resulting reaction mixture was heated at 145° C. for 16 h, after which time it was quenched with H2O (30 mL) and diluted with EtOAc (200 mL). The EtOAc solution was washed with H2O (3×100 mL), then brine (100 mL) and dried (MgSO4), filtered, and concentrated in vacuo. The resulting residue was chromatographed on silica gel eluting with hexane:EtOAc (40:60) to afford 3-(3-pyridin-2-yl-1H-1,2,4-triazol-1-yl)benzonitrile as a white solid.
