Reaction Steps

Ethyl 4,4,4-trifluoroacetoacetate (350 g), under a blanket of nitrogen gas, was heated to 40° C. and treated with platinum (0.7 g of 5% Pt/C, 0.01% load) and triethylamine (1.5 g, 0.4% load). Hydrogen was charged to a pressure of 5 bars and the mixture agitated at 40° C. for 6h. After filtration to remove the catalyst, 341 g (96% yield) of ethyl 4,4,4-trifluoro-3-hydroxybutyrate was obtained.
