Claims
- 1. A process for making N-(N'-methylenepyrrolidonyl)-2-substituted aniline intermediate compounds in high yield having the formula: ##STR5## where R is alkyl, C.sub.1 -C.sub.6,
- alkenyl, C.sub.3 -C.sub.5,
- alkyleneoxyalkyl, --(CH.sub.2).sub.n OR", where n=1-3, and
- R" is alkyl, C.sub.1 -C.sub.3, or cycloalkyl, ##STR6## where n'=0-3, R' is hydrogen or alkyl, C.sub.1 -C.sub.3, and,
- Y is oxygen or sulfur,
- which consists of:
- (a) forming a mixture containing substantially equivalent molar amounts of a chloromethylpyrrolidone having the formula: ##STR7## and a 2-substituted aniline having the formula: ##STR8## by adding said chloromethylpyrrolidone to said 2-substituted aniline at a temperature of about 5.degree. C. or less, at atmospheric pressure, in an aromatic hydrocarbon solvent, in the presence of an acid acceptor, and
- (b) warming said mixture to about room temperature
- (c) reacting said reactants until alkylation is substantially complete, and,
- (d) crystallizing the product from the resulting solution.
- 2. A process according to claim 1 wherein R is alkenyl.
- 3. A process according to claim 1 wherein said solvent is toluene or xylene.
