Water → 5-Nitro-2-[[(1-propylimidazol-5-yl)methyl]sulfanyl]pyridine

Participants

Reaction Steps

2-mercapto-5-nitropyridine (2.3 g) was dissolved in DMF (47 ml), potassium carbonate (6.2 g) and 5-chloromethyl-1-propylimidazole hydrochloride (3.5 g) was added to the mixture, and the mixture was stirred for 40 hours at room temperature. The reaction solution was added to water, and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure, and the obtained residue was purified by silica gel column chromatography, to give 5-nitro-2-[[(1-propylimidazol-5-yl)methyl]sulfanyl]pyridine (2.9 g).
