Reaction Steps

The procedure described in Example 3 was followed, using 1-(3-aminopropyl)-4-(4-chlorobenzyl)piperazine (2.67 g; 10 mmole), methylene chloride (50 ml) and 4-chlorophenyl isocyanate (1.54 g; 10 mmole). Recrystallization from methanol provided the title compound (1.1 g; 25% yield) as colorless crystals, m.p. 241° C.
