Versuchsvorschrift

According to Carter and Blattacharye [J. Amer. Chem. Soc 75, 2503 (1953)], D,L-carnitine is obtained by reacting benzaldehyde, epichlorohydrin and ammonia in an organic solvent, the reaction product 2-phenyl-5-chloromethyloxazolidine is isolated and said compound is subsequently transformed into D,L-carnitine according to known techniques, with a yield of 20-25%.
