Reaction Steps
3.1 g (0.05 mol) of sodium oxide (Na2O) are suspended in 150 ml of 1,2-dimethoxyethane, and then 18.5 g (0.1 mol) of N-trimethylsilylcaprolactam are added. The reaction mixture is stirred at 50° C. for two hours, during which the voluminous precipitate of the sodium salt of the caprolactam forms. Then 24.9 g (0.1 mol) of n-dodecyl bromide are added, and the mixture is stirred and heated under reflux for 20 hours. The working-up is carried out as indicated in Example 1.
