반응 단계
Ethyl 4,4,4-trifluoroacetoacetate (50 g), under a blanket of nitrogen gas, is heated to 40° C. and treated with platinum (0.1 g of 5% Pt/C, 0.01% load) and methanesulfonic acid (1.5 g, 2.9% load). Hydrogen is charged to a pressure of 5 bars, and the mixture agitated at 40° C. for 6h. After filtration to remove the catalyst, 25.3 g (50% yield) of ethyl 4,4,4-trifluoro-3-hydroxybutyrate is obtained.
