Pentanoic acid, 2-bromo- → 1,3-bis(4-carboxybutyl)-4,5-dichloro-1H-imidazol-3-ium bromide

Participants

Reaction Steps

4,5-dichloroimidazole (1.00 g, 7.36 mmol) was dissolved in acetonitrile. Potassium hydroxide (0.828 g, 14.72 mmol) was added to the solution and allowed to reflux for 30 min. 2 equivalents of 2-bromopentanoic acid (2.66 g, 14.72 mmol) was added to the solution and refluxed for 5 h. Solution was filtered to remove the KBr precipitate and neutralized with 6M HBr. Volatiles were removed in vacuo and the resulting product will be collected and analyzed.
