A solution of 2[(N-methyl-N-n-octadecylamino)methyl]-2-propenenitrile (1.7 g., 0.005 mole) in 10 ml. of acetone is mixed with propionic acid (0.41 g., 0.0055 mole). The solvent is stripped in vacuo, and the residue is dissolved in a small volume of ether. Low boiling petroleum ether is gradually added until the ice cold solution became turbid. After standing at 10° C. for 12 hours the product is removed by suction filtrations and then washed with cold petroleum ether followed by drying at ambient temperature.
