Similarly to Example 3, a solution of 1-amino-4-(6-chloronaphthalene-2-sulfonyl)-2-piperazinone (510 mg) and 1-(3-pyridyl)-4-piperidone (260 mg) in toluene (20 ml) was refluxed for 7 hours. The reaction mixture was cooled to room temperature, and the resultant crystal was collected by filtration to obtain the title compound (480 mg) as colorless crystals.
