Reaction Steps

A 1.82 g quantity of (E)-3-[2-(3-benzyloxy-4-methoxyphenyl)oxazol-4-yl]-1-(2-propoxyphenyl)-2-propen-1-one obtained in Example 193 was dissolved in 50 ml of methanol. A 200 mg quantity of 5% palladium-carbon powder was added thereto, and the mixture was stirred under a hydrogen atmosphere at room temperature for 2 hours. The catalyst was then removed by filtration. The filtrate was diluted with 100 ml of methanol, and 500 mg of 10% palladium-carbon powder was added thereto. The mixture was stirred under a hydrogen atmosphere at room temperature for 3 hours. The catalyst was removed by filtration, and the solvent was removed under reduced pressure. Diisopropyl ether was added to the residue for crystallization to give 0.78 g of colorless powdery 3-[2-(3-hydroxy-4-methoxyphenyl)oxazol-4-yl]-1-(2-propoxyphenyl)propan-1-one.
