Reaction Steps

4-(2-isopropoxyethoxy)benzaldehyde obtained in step (0.98 g, 4.71 mmol) and 2,4-thiazolidinedione (0.55 g, 4.71 mmol) were dissolved in 20 ml of toluene, piperidine (0.23 ml, 2.36 mmol) and acetic acid (0.13 ml, 2.36 mmol) were subsequently added thereto, and the resulting solution was heated overnight under reflux in a Dean-Stark water trap. Then, the mixture thus obtained was cooled and filtered. The precipitate was washed with ether or hexane and dried to afford Derivative 1 having the above formula, (5-(4-(2-isopropoxyethoxy)benzylidene)thiazolidine-2,4-dione) (1.26 g, yield: 87.5%) as yellow solid.
