실험 절차

By following the same procedure as described in Example 1, methyl 3-{4-[2-acetoxy-2-(5-ethyl-2-pyridyl) ethoxy]phenyl}-2-bromopropionate (10.0 g), thiourea (2.0 g) and sodium acetate (2.2 g) were allowed to undergo reaction in ethanol and hydrolysis was performed to give 5-{4-[2-(5-ethyl-2-pyridyl)-2-hydroxyethoxy]benzyl}-2,4-thiazolidinedione in the form of crystals. Yield of 6.2 g. Recrystallization from ethyl acetate-hexane produced colorless prisms. m.p. 129°-130° C.
