Procedure

Using an analogous procedure to that described in Example 1, 1-(4-pyridyl)piperidine-4-carbonyl chloride was reacted with ethyl 1-benzylpiperazine-2-carboxylate (Helv. Chim. Acta, 1962, 45, 2383) to give 1-benzyl-2-ethoxycarbonyl-4-[1-(4-pyridyl)piperidin-4-ylcarbonyl]piperazine in 67% yield.
