Versuchsvorschrift

Using an analogous procedure to that described in Example 1 except that DMF was used in place of methylene chloride as the reaction solvent, 1-(4-pyridyl)piperidine-4-carbonyl chloride was reacted with 1-(2-naphthylmethyl)-2-oxopiperazine trifluoroacetate salt to give 1-(2-naphthylmethyl)-2-oxo-4-[1-(4-pyridyl)piperidin-4-ylcarbonyl]-piperazine in 18% yield;
