Versuchsvorschrift

To a cold solution of 67 g (0.47 mole) of methyliodide in 150 ml of anhydrous ether was added slowly a dry ether solution of 50 gm of 2-(N,N-dimethylaminomethyl)pyrrole (0.37 mole). A white solid begain to precipitate out of solution. The mixture was heated to 30° for 1.5 hours, filtered and washed with 2/×30 ml of ether to obtain 59 gm of 2-pyrryl)methyltrimethylammonium iodide which was used in the next step without further purification.
