Versuchsvorschrift

21.5 g of Boc-Ala-Oic-OBzl are dissolved in 50 ml of trifluoroacetic acid. The solution is concentrated in vacuo, and the residue is digested several times with diisopropyl ether and is dried in vacuo. Yield: 21 g. The proton signal for the tertiary-butyl group is completely absent in the NMR spectrum.
