Reaction Steps
2-piperazinone was suspended in a mixed solvent of dichloromethane and dioxane and then pyridine and benzenesulfonyl chloride were added thereto. After stirring at room temperature for 16 hours, the solvent was removed by evaporation and the resulting solid was suspended in 1N hydrochloric acid, filtered, and washed with diisopropyl ether to obtain 4-(phenylsulfonyl)-2-piperazinone.
