Reaction Steps

A solution of 2-cyanopyridine (0.18 mL, 1.86 mmol) in methanol (5 mL) was treated with sodium metal (12.8 mg, 0.56 mmol) a stirred at ambient temperature for 1 hour. The reaction mixture was then treated with a solution of 3-cyanobenzhyrazide (0.30 g, 1.86 mmol) in methanol (5 mL) and heated at reflux for 3 hours. The reaction mixture was then concentrated in vacuo. The resulting yellow solid was dissolved in toluene (2 mL) and heated overnight at 175° C. The reaction mixture was concentrated in vacuo. Silica gel chromatography using 2% methanol in dichloromethane afforded 0.12 g (26%) of 2-(2-pyridyl)-5-(3-cyanophenyl)-1,3,4-triazole.
