Reaction Conditions

Reaction Steps

47 g pyrrolidine, 149.5 g 1-bromododecane and 83 g potassium carbonate were added to 560 mL acetone. The reaction mixture was heated at 55° C. for 24 hr, then filtered. Solvent was removed from the filtrate, yielding 92 g N-dodecylpyrrolidine. 80 g N-dodecylpyrrolidine and 52.6 g 1-bromo-3-chloropropane were dissolved in 133 mL methanol and the reaction mixture was heated at 65° C. for 18 hr. After cooling to room temperature, methanol was removed under reduced pressure. The residue was poured into 2 L diethylether with stirring and the mixture was allowed to stand for another 6 hr. The white precipitate thus formed was filtered and was dried at 40° C. under a vacuum for 24 hr yielding 85 g (3-chloropropyl)dodecylpyrrolidinium bromide as a white solid.
