Versuchsvorschrift

52 g of ethyl (2-hydroxyethyl)-n-butylcarbamate are placed in 125 ml of methylene chloride and treated dropwise with 41.6 g of thionyl chloride during 45 minutes at 20°-25° C. Then the mixture is allowed to react for an additional 1 hour at room temperature. After removing the solvent, the residue is distilled to yield pure ethyl (2-chloroethyl)-n-butylcarbamate; b.p. 91° C./0.07 Torr.
