<p>A process for preparing N,N-dimethyl-2-¢5'-oxo-2'-pyrrolidine!ethylamine, or the N-oxide thereof, which comprises reacting 5-oxo-2-pyrrolidine-acetonitrile with hydrogen and dimethylamine in the presence of a palladium catalyst and, when the N oxide is required, oxidizing the N,N-dimethyl-2-¢5'-oxo-2'-pyrrolidine!ethylamine product of said reaction. the compounds are useful in the preparation of 5-vinyl-2-pyrrolidinone which can be hydrolysed to 4-amino -5-hexenoic acid.</p> |
