Procedure
0.036 moles (10.3 g) N-(3-dimethylaminopropyl)-lauramide and 25 ml acetone were placed in a 100 ml round bottom flask. 0.036 moles (3.4 ml) dimethylsulfate was added slowly to the flask, a condenser attached, and the reaction mixture refluxed for two hours. After cooling, the product crystallized out of the acetone, was filtered off, and recrystallized from acetone to a constant melting point. Melting point 98.5°-100° C.
