With regard to the dimethylamino compound, said compound is prepared by employing the procedure set forth in Example 3, with the exception that 1-ethyl-2-methyl-5-nitroimidazole is utilized instead of 1,2-dimethyl-5-nitroimidazole. The process yields 1-ethyl-5-nitro-2-imidazolecarboxaldehyde, 4',4'-dimethyl-3'-thiosemicarbazone, which is cyclized as in Example 3 to 2-(2-dimethylamino-5-thiadiazoly)- 1-ethyl-5-nitroimidazole.
