The synthesis of a series of 1-aminoalkyl-2-benzyl-nitro-benzimidazoles is described. Many of the 5-nitro-benzimidazoles prepared show strong analgesic activity. 1-(β-Diethylamino-ethyl)-2-(p-ethoxy-benzyl)-5-nitro-benzimidazole (XXXVIII) is 1000 times as potent as morphine and therefore the most active analgesic known until now.
