Versuchsvorschrift

3,3,3-trifluoropropanoic acid (0.24 mmol) was dissolved in dry DCM (0.5 mL) in a 4 mL vial, added oxalyl chloride (0.24 mmol) and a catalytic amount of DMF. Stirred at rt for 1 h and added to a mixture of intermediate 4 (0.05 mmol) and Et3N (0.47 mmol) in dry DCM (0.5 mL). Stirred at rt for 16 h. Reaction mixture filtered through a syringe filter, added TFA (1 mL) and stirred at rt for 15 min. Reaction mixture added H2O (5 mL) and extracted with DCM (3×5 mL). The organic phase was dried (Na2SO4), filtered, concentrated in vacuo and redissolved in DMSO (1 mL). The pure compound was obtained by standard preparative HPLC purification.
