실험 절차
Into 20 ml of ethanol were suspended 0.50 g of 5-(4-aminophenyl)-thiazolidine-2,4-dione, and, after added 0.42 g of 3,4-dichlorobenzaldehyde thereto, the suspension was refluxed for 3 hours. After cooling by standing, the crystals deposited were collected by filtration. The crude crystals were recrystallized from ethanol to obtain 0.79 g of title compound.
