LIGHT BEIGE FINE CRYSTALLINE POWDER | [Uses]
2-Benzimidazoleacetonitrile, is used as a pharmaceutical intermediate. It is also used as an intermediate in organic synthesis. | [Safety Profile]
Poison by intravenous route. Seealso NITRILES. When heated to decomposition it emitstoxic fumes of NOx. | [Synthesis]
To the dry solid of o-phenylenediamine (1.08 g, 10 mmol) was added ethyl cyanoacetate (1.13 g, 10 mmol). The reaction mixture was placed in an oil bath and heated at 120 °C for 30 min, followed by cooling to room temperature. Upon completion of the reaction, the product was collected by filtration and ground with diethyl ether for purification. Finally, recrystallization was carried out from ethanol to give 2-cyanomethylbenzimidazole. | [References]
