Reaction Steps

1.5 g (33.4 mmole) 5-(4-[2-(3-methoxy-4-methanesulfonyloxyphenyl)ethoxy]benzylidene)thiazolidine-2,4-dione was hydrogenated on Pd/C (10%) in 150 ml ethyl acetate and 5 ml acetic acid at atmospheric pressure over night. The catalyst was filtered off and the solvent was evaporated in vacuo. The residue was crystallized in ethanol to give 1.1 g (yield 73%) of the desired product.
