Reaction Steps
7 g (18.7 mmole) of 4-[2-(4-formylphenoxy)ethyl]phenyl trifluoromethanesulfonate, 2.74 g (23.4 mmole) 2,4-thiazolidinedione and 3.8 g (46.8 mmole) sodium acetate were mixed and heated under vacuum to 140° C. when it melted. It was kept at 140° C. for 20 minutes and thereafter taken off the heat, water:acetone (2:1) was added, the formed crystals were filtered off and recrystallization in dichloromethane gave 2.09 g (yield 24%) 5-(4-[2-(4-trifluoromethanesulfonyloxyphenyl)ethoxy]benzylidene)thiazolidine-2,4-dione.
