Reaction Steps
The procedure described in Example 29 was followed using n-dodecyl isocyanate (2.11 g; 10 mmole), 1-(3-aminopropyl)-4-(4-chlorobenzyl)piperazine trihydrochloride (3.77 g; 10 mmole) methylene chloride (100 ml), and triethylamine (3.03 g; 30 mmole). Recrystallization from water provided the title compound (3.21 g; 58% yield) as colorless crystals, m.p. 215°-222° C.
