Reaction Steps

The procedure described in Example 3 was followed, using 1-(3-aminopropyl)-4-(4-chlorobenzyl)piperazine trihydrochloride (3.77 g; 10 mmole), tetrahydrofuran (50 ml), triethylamine (4.2 ml; 30 mmole) and n-hexyl isocyanate (1.41 g; 10 mmole). Recrystallization from ethanol provided the title compound (4.00 g; 83% yield) as colorless crystals, m.p. 214°-215° C.
