Versuchsvorschrift
Propylmethylpyrrolidinium bromide was prepared by Menshutkin reaction of N-methylpyrrolidine with 1-bromobutane. 21.5 g of the adduct formed by the IB-4 complex with KF were added to 20.8 g of [C4H8N(CH3)C3H7]Br in 100 ml of acetone. The suspension was stirred by means of a magnetic stirrer for 48 hours. The KBr formed during the reaction was eliminated by filtration and the precipitate was washed with two portions of 20 ml of acetone. The solvent was eliminated and a viscous liquid was recovered, corresponding to the formula:
