실험 절차
1.5 g (4.7 mmole) 4-[2-(4-formylphenoxy)ethyl]phenyl methanesulfonate, 0.68 g (5.8 mmole) 2,4-thiazolidinedione and 0.96 g (11.8 mmole) sodium acetate were mixed and heated under vacuum to 155° C. The reaction mixture melted and was removed from the heat after 15 minutes. Water/acetone (2:1) was added and the mixture was stirred for 1 h. Filtration gave 1.67 g (yield 83%) of 5-(4-[2-(4-methanesulfonyloxyphenyl)-ethoxy]benzylidene)thiazolidine-2,4-dione as yellow crystals.
