Versuchsvorschrift
Suspend Boc-(L)-Pal-NH2 (0.98 g) in methylene chloride (15 mL) with light heating and add a solution of hydrochloric acid (4M, 10 mL) in dioxane. After 30 minutes evaporate methylene chloride and dioxane. Dissolve the solid in methanol, precipitate by addition of ether and filtrate to give H-(L)-Pal-NH2. 2HCl (0.86 g, 98%).
