Procedimiento

Pyridine and excess n-butyl chloride were heated under reflux in nitromethane for 24 hours and then cooled, and the reaction solution was poured into dioxane, thereby precipitating the crystals formed. Thus, crude crystals of butylpyridinium chloride (BPC) were obtained. These were purified by recrystallizing them in methanol/dioxane solvent two or three times and then fully dried in vacuum.
