Versuchsvorschrift

To a suspension of glycine hydrochloride (400 g, 3.58 mol) in n-butanol (8 L), thionyl chloride (1.37 L, 18.84 mol) was added slowly dropwise. After addition was complete, the reaction was heated at 70° C. overnight. The product mixture was concentrated under vacuum and the residue was triturated with a mixture of heptane/ethyl acetate. The white solid precipitated was filtered and dried under a stream of dry nitrogen to provide the title compound.
