Reaktionsschritte

1.7 g (8.5 mmol) of ethyl 2-amino-4,4,4-trifluoro-3-hydroxybutyrate were dissolved in THF, and initially 1.8 g of 4-fluoro-2-trifluoromethylbenzoic acid and 2.6 g (25.4 mmol) of triethylamine and then, at 5° C., 1.9 g (8.5 mmol) of bis(2-oxo-3-oxazolinidylphosphoryl chloride were added. The mixture was stirred at RT for 16 h. The reaction solution was then concentrated, and the residue was diluted with water and extracted with ethyl acetate. The combined organic phases were dried and the solvent was removed. This gave 3.1 g (93% of theory) of the title compound as a colorless residue.
