To a solution of carnitine hydrochloride (9 grams; 0.045 moles) in 15 cc of trifluoroacetic acid, 0.13 moles of allyl acetyl chloride were added. The resulting solution was kept at 45° C. for 4 hours. Subsequently, acetone was added to the solution, the unreacted carnitine was separated and ethyl ether was added, thus obtaining a precipitate. The raw material thus obtained was purified by precipitation from isopropanol--ethyl ether. 9.5 grams of product were obtained. Yield 66%.
