Reaktionsschritte
Wedler, et al. (Journal. f. prakt. Chemie (1990) 332:557–562) discuss a process for producing 5-hydroxy-1,5-dimethyl-2-pyrrolidone by reacting α-angelica lactone with methylamine. Dehydration of this product resulted in the formation of the unstable 5-methylene-N-methyl-2-pyrrolidone, rather than the desired 1,5-dimethyl-2-pyrrolidone.
