Cis-4-[4-(5-chloro-2-methylphenyl)piperazinyl]-2-buten-1-amine: according to the method of Example 5, phthalimide potassium salt was reacted with cis-1,4-dihydro-2-butene to obtain N-(cis-4-chloro-2-buten-1-yl)phthalimide; which was then reacted with 5-chloro-2-methylphenylpiperazine to obtain N-{4-[4-(5-chloro-2-methylphenyl)piperazinyl]-cis-2-buten-1-yl}phthalimide, which was then reacted with hydrazine hydrate. Yield: 85.7%.
