Abstract

Process for the manufacture of substituted pyrrolidones, which comprises transforming a 4-aryl-2-pyrrolidone, which can carry alkyl groups in positions 3 and 4, into a compound of the general formula ** (See formula) ** in which n represents an integer from 1 to 6, R1 and R2 each represent hydrogen or alkyl, and R3 and R4 each represent hydrogen or alkyl or, together with the nitrogen atom, a 5- or 6-membered heterocyclic ring, and, if desired, converting the product thus obtained into an acid addition salt.
