Versuchsvorschrift
To a 200 mL round bottom flask were added N-[3-(1-methylpiperidin-4-yl)-propyl]-N,N′,N″-tri-Boc-guanidine prepared as in Example 27 above (3.20 g, 0.0064 mol) and 1,4-dioxane (anhydrous, 50 mL). To the resultant stirred solution was added 4.0 M HCl in 1,4-dioxanes (6.42 mL, 0.026 mol) drop wise over 2.0 min. The resultant mixture was then warmed to 75° C., aged for 3 h then cooled to 0° C. A precipitate was formed. The bulk solvent was decanted and the solids were dried under vacuum for 12 h to yield N-[3-(N-methyl-4-piperidinyl)-1-propyl]guanidine, as its corresponding HCl salt.
