反应详情

10 g of 3-(4-hydroxyphenyl)pyruvic acid were dissolved in 50 ml of methanol, and 0.05 g of platinum oxide was added thereto. The mixture was stirred at 25° C. under atmospheric pressure for 6 hours in a hydrogen stream. After completion of the reaction, the catalyst was removed by filtration, and the filtrate was concentrated under reduced pressure to give 10.1 g of 3-(4-hydroxyphenyl)lactic acid as colorless crystals.
