Reaction Steps

A mixture of 5-formyl-2-[2-(5-methyl-2-phenyl-4-oxazolyl) ethoxy]pyridine (0.6 g), 2,4-thiazolidinedione (0.235 g), piperidine (0.066 ml) and ethanol (20 ml) was heated for 9 hours while refluxing. The reaction mixture was poured into water; the separating crystal, collected by filtration, was then recrystallized from ethanol-chloroform to yield 5-[[2-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]-5-pyridyl]methylidene]-2,4-thiazolidinedione (0.232 g, 29%) as a yellow crystal.
