Potassium Hydroxide → HCID 70983740, compound

Participants

Reaction Steps

4,5-Dichloroimidazole (2.00 g, 14.6 mmol) was dissolved in 15 mL acetonitrile in a round bottom flask. Potassium hydroxide (0.90 g, 16.0 mmol) was added and the mixture was refluxed for 15 min. Concurrently, 2-chloromethylquinoline hydrochloride (3.13 g, 14.6 mmol) and potassium hydroxide (0.82 g, 14.6 mmol) were added to a second round bottom flask and stirred in 60 mL acetonitrile at reflux for 10 min. The contents of the second flask were added to the first, and the combined mixture was refluxed overnight, during which time a white precipitate formed. The reaction mixture was filtered hot, yielding a clear, tan filtrate. Slow evaporation and cooling of the filtrate yielded tan crystals of 1-(quinolin-2-ylmethyl)-4,5-dichloroimidazole, which were collected by a second filtration. The crystals (0.278 g, 1.0 mmol) will be dissolved in a minimum volume of DMF. Iodomethane (0.62 mL, 10.0 mmol) will be added and the mixture will be heated at 80° C. for 12 h. Removal of the volatile components under reduced pressure will yield the product.
