108 g of freshly distilled butyraldehyde were added dropwise at 0° C. to a mixture of 213 g of pyrrolidine and 213 g of potassium carbonate. The mixture was allowed to stand overnight at room temperature, diluted with 300 ml of toluene, and the residue was filtered off. The filtrate was then subjected to vacuum distillation at 85° to 90° C. (80 mbar), giving 102 g of 97% pure 1-pyrrolidinobutene, which corresponds to 63.7% of the theoretical yield).
