Abstract
There is disclosed a method for the production of 1-n-dodecylazacycloheptan-2-one by reacting caprolactam with 1-bromododecane in the presence of a phase transfer catalyst under anhydrous conditions using a nonpoisonous hydrocarbon as solvent. The method is a one-pot synthesis employing solid-liquid phase transfer catalysis.
