Versuchsvorschrift

L-Phenylalanyl-L-prolinamide hydrobromide (480 mg) was dissolved in DMF (3 ml), to which was added triethylamine (0.29 ml) under cooling at -10° C. The mixture was stirred for 10 minutes under ice-cooling and the resultant precipitate was filtered off to give L-phenylalanyl-L-prolinamide in DMF solution, which was immediately used for the next reaction.
