1-Methylimidazole is used as a precursor for the synthesis of pyrrole-imidazole polyamides, ionic liquids such as 1-butyl-3-methylimidazolium hexafluorophosphate. It is actively involved in removing acid during the production of diethoxyphenylphosphine. It is used as an intermediate in organic synthesis.
Useful base for peptide coupling, etc. See, e.g.: J. Chem. Soc., Chem. Commun., 2223 (1995). For peptide reagents, see Appendix 6.
Undergoes lithiation at the 2-position. Reaction of the Li derivative with ketones followed by dehydration with acetic anhydride is a good route to 2-alkylideneimidazoles: Synthesis, 78 (1990). Likewise, reaction with benzonitrile gives the 2-benzoyl derivative, the carbonyl group of which undergoes Wittig methylenation: Synth. Commun., 20, 321 (1990).
Reacts with acid chlorides, including chloroformates, to give N-acylimidazolium salts, which are useful reagents for the acylation of, for example, amino acids: Bull. Soc. Chim. Fr., 1021 (1973).
