Procedure

N,O-dimethylhydroxyamine hydrochloride (3.5 g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (6.9 g) and triethylamine (9.2 mL) were added to a solution of 4,5,5-trifluoropent-4-enoic acid (CAS No. 110003-22-0 (5.0 g)) in methylene chloride solution (64 mL) in a cold-water bath and stirring was carried out at room temperature overnight. The reaction solution was concentrated and diluted with ethyl acetate. The dilute solution was washed with 1 N hydrochloric acid, water and saturated brine; dried with anhydrous sodium sulfate; and concentrated to obtain the title compound (6.4 g) having the following physical properties:
