ABSTRACT:
A process for producing a lactone-substituted aniline wherein an alpha-halo-gamma-butyrolactone is reacted with an aniline in the presence of water at a temperature between 80.degree. and 160.degree. C. Thus, 3-(N-2,6-dimethylphenylamino)-gamma-butyrolactone is prepared by reacting an alpha-halo-gamma-butyrolactone with 2,6-dimethylaniline in the presence of water and an inert organic solvent at a temperature between 80.degree. and 160.degree. C. This process is advantageously combined with a subsequent acylation step to provide a continuous means for making materials such as 3-(N-chloroacetyl-N-2,6-dimethylphenylamino)-gamma-butyrolactone.
