Procedure

4-(2′-Methoxybenzylidene)-2-methyl-4H-oxazol-5-one (2.4 g) was dissolved in ethanol (50 ml) and aqueous ammonia (20 ml) and potassium carbonate (3 g) were added. The mixture was heated at 80° C. for 10 hr. After cooling, the solvent was evaporated under reduced pressure and water was added to the residue. The mixture was extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The precipitated yellow crystals were collected by filtration to give the title compound (2 g).
