実験手順
A solution of 2 g of bis-4,4'-(1,4-piperazinediyl)dibenzaidehyde in 100 ml of acetone is treated dropwise with 100 ml of Jones' reagent. The mixture is stirred at room temperature for 1 hour and then poured into 100 ml of water. The precipitate which thereby results is filtered off, washed portionwise with water and dried in a vacuum. The crude product is recrystallized from ethanol and yields pure bis-4,4'-(1,4-piperazinediyl)dibenzoic acid.
