Procedure: To a solution of N-[3-(4-benzyl-1-piperazinyl)propyl]phthalimide (22.4 g) in ethanol (250 m) was added 100% hydrazine hydrate (8.02 g). The resulting mixture was refluxed with stirring for 2.5 hours. The reaction mixture was cooled and then filtered. The filter cake was washed with ethanol. The filtrate and washing were combined and evaporated under reduced pressure. To the residue was added 5% aqueous solution of potassium hydroxide and the mixture was extracted with chloroform. The extract was washed with water, dried over magnesium sulfate and then evaporated under reduced pressure to give an oil of 3-(4-benzyl-1-piperazinyl)propylamine (12.4 g). The resulting mixture was refluxed The reaction mixture was cooled filtered The filter cake was washed with ethanol The filtrate and washing evaporated under reduced pressure To the residue was added 5% aqueous solution of potassium hydroxide the mixture was extracted with chloroform The extract was washed with water dried over magnesium sulfate evaporated under reduced pressure

Procedure: A solution of 1-(3-aminopropyl)-4-benzylpiperazine (3.0 g; 12.9 mmole) and phenyl isocyanate (1.54 g; 12.9 mmole) in methylene chloride (20 ml) was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure, and the residue was crystallized from aqueous acetone to provide the title compound as colorless crystals (2.77 g; 61% yield), m.p. 45°-47° C. The reaction mixture was concentrated under reduced pressure the residue was crystallized from aqueous acetone

Procedure: A solution of 1-(3-aminopropyl)-4-benzylpiperazine (2 g; 12.9 mmole) and cyclohexyl isocyanate (1.6 g; 12.9 mmole) in methylene chloride (50 ml) was stirred overnight at room temperature. The reaction mixture was concentrated, and the crude product was precipitated as the dihydrochloride from ether in the manner described in Example 6. Recrystallization from ethanol provided the title compound as colorless crystals (3.62 g; 65% yield), m.p. 202°-213° C. The reaction mixture was concentrated the crude product was precipitated as the dihydrochloride from ether in the manner Recrystallization from ethanol
