Nitration gives 5-nitro derivative. [1] 2-Methylimidazole is a sterically hindered imidazole that is used to simulate the coordination of histidine to heme complexes. It can be deprotonated to make imidazolate-based coordination polymers. [2]
Structures with names 4- and 5-nitroimidazole are equivalent from the perspective of drugs since these tautomers readily interconvert. Drugs of the 5-nitro variety include metronidazole, tinidazole, nimorazole, dimetridazole, pretomanid, ornidazole, megazol, and azanidazole. Drugs based on 2-nitroimidazoles include benznidazole and azomycin. [3]
2-Methylimidazole (1) may be prepared via the Debus-Radziszewski imidazole synthesis, or from ethylenediamine and acetic acid, followed by treatment with lime, then Raney nickel. 2-Methylimidazole is nitrated to give 2-methyl-4(5)-nitroimidazole (2), which is in turn alkylated with ethylene oxide or 2-chloroethanol to give metronidazole (3 ...

1-Methylimidazole or N-methylimidazole is an aromatic heterocyclic organic compound with the formula CH 3 C 3 H 3 N 2. It is a colourless liquid that is used as a specialty solvent, a base, and as a precursor to some ionic liquids.
We even spotted a pair of best-selling Crocs with more than 1,800 reviews and an almost unheard of perfect 5-star rating on sale for just $30. But there's more where those came from.
