To a solution of 1.75 g (10.0 mmol) of an aldehyde derivative (2) in 20 mL of toluene were added 1.13 g (10.0 mmol) of rhodanine-3-propionic acid and 2.5 g (30.0 mmol) of piperidine, followed by stirring under reflux for 2.5 hours. After completion of the reaction, the mixture was cooled to room temperature, diluted with 100 mL of toluene, supplemented with 100 mL of water, and stirred. After the whole had been left to stand still, an organic layer was separated and dried over anhydrous sodium sulfate. After filtration, toluene was distilled off under reduced pressure, and recrystallization of the residue from ethanol afforded 1.6 g (yield: 43.2%) of a target product (8).
