Procedure
The procedure described in Example 29 was followed, using 4-ethoxyphenyl isocyanate (1.63 g; 10 mmole), 1-(3-aminopropyl)-4-(4-chlorobenzyl)piperazine trihydrochloride (3.77 g; 10 mmole), methylene chloride (16 ml), and triethylamine (4.3 ml; 31 mmole). Recrystallization from ethanol provided the title compound (3.42 g; 68% yield) as colorless crystals, m.p. 225°-227° C.
