5-Nitrobenzimidazole (0.109 moles, 17.8 g.) was reacted with sodium hydride (0.122 moles, 4.9 g of 60% in mineral oil) and ethyl 2-bromooctanoate (0.102 moles, 22 ml) as in Example 11 to produce a mixture of the 5 and 6 isomer. The isomers were separated to yield 7.8 g of ethyl 2-(5-nitro-1H-benzimidazol-l-yl)octanoate.
