ABSTRACT:
In a method of synthesis of 1-substituted azacycloalkan-2-ones with primary alkyl halides and aralkyl halides as alkylating agents, the improvement comprising carrying out the N-alkylation in the presence of a phase transfer catalyst having the structural formula ##STR1## where X is suitable anion; and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each alkyl or aralkyl groups having 1-18 carbon atoms, or R.sub.2, R.sub.3 and R.sub.4 can form a part of a heterocyclic ring, with the proviso that the combined total of carbon atoms is between 16 and 40.
