실험 절차
A solution of 5-cyanobenzimidazole (1.43 g; 10 mmol; 1 eq.) in EtOH (30 ml) was treated with K2CO3 (2.76 g; 20 mmol; 2 eq.) and hydroxylaminehydrochloride (765 mg; 11 mmol; 1.1 eq.) and heated to reflux over night. After cooling to room temperature, the mixture was diluted with Et2O. The resulting solid was collected by filtration, washed with Et2O and water and used without further purification. Yield: 1.28 g (72.7%); MS m/z: 177.3 [M+H]+
