실험 절차

A mixture of 2-chloro-4-nitro-1H-benzimidazole (300 mg) and N,N-dimethylethylenediamine (2 ml) were stirred at 80° C. for 8 hours. The reaction mixture was poured into saturated sodium bicarbonate aqueous solution and extracted with a mixture of chloroform and methanol. The organic layer was washed with brine, dried over magnesium sulfate and evaporated in vacuo. The residue was washed with diisopropyl ether to give 2-[[2-(dimethylamino)ethyl]amino]-4-nitro-1H-benzimidazole (113 mg).
