Reaction Steps
The procedure described in Example 21 was followed, using 4-cyanophenyl isocyanate (1.44 g; 10 mmole), 1-(3-aminopropyl)-4-(4-chlorobenzyl)piperazine trihydrochloride (3.77 g; 10 mmole), methylene chloride (75 ml) and triethylamine (4.3 ml; 31 mmole). Recrystallization from methanol/ethanol provided the title compound (3.87 g; 77% yield) as colorless crystals, m.p. 236°-238° C.
