Versuchsvorschrift

To a solution of 4,4,5,5,5-pentafluoropentanoic acid (6.44 g, 33.5 mmol) and the intermediate from Step E (5.0 g, 27.9 mmol) in DCM (100 mL) was added EDC (7.49 g, 39.1 mmol) followed by DIEA (24.4 mL, 140 mmol). After stirring the reaction at room temperature for 2 hours, it was diluted with DCM (100 mL), and washed with water (2×). The organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered, and concentrated to give a colorless oil. m/z=316.8 (M+H).
