Versuchsvorschrift
Under a nitrogen atmosphere, a solution containing 13.0 g. (0.12 mole) of N-methyl-N-propargylacetamide, 5.8 g. of paraformaldehyde, 10.5 g. (0.15 mole) of pyrrolidine and a trace of cuprous chloride in 80 ml. of dioxane was refluxed for 5 hrs. and allowed to stand overnight. The mixture was filtered remaining oil was distilled and redistilled giving N-methyl-N-(4-pyrrolidino-2-butynyl)acetamide, boiling at 120° C. at 0.03 mm.
