Conditions

Temperature: 65 °C

Procedure

A mixture of 22 g of diallylmethylamine and 75 g 4-chlorobutyldimethyldodecylammonium bromide was dissolved in 100 mL of methanol and the reaction mixture was stirred at 65° C. for 48 hours. After cooling to room temperature, the solvent was removed under reduced pressure. The residual viscous oil was precipitated into 800 mL of ether with rapid stirring. The ether layer was decanted and the residue was again treated with 500 mL of ether. After stirring for 15 minutes the solvent was removed and the oily residue was dried under vacuum at 35° C. for 48 hours, yielding 65 g of the product.
