Cyanoacetic acid → Perfluorophenyl 2-cyanoacetate

Participants

Reaction Steps

To a solution of 2,3,4,5,6-pentafluorophenol (1.08 g, 5.88 mmol) and 2-cyanoacetic acid (0.50 g, 5.9 mmol) in DCM (20 mL) was added DCC (1.21 g, 5.88 mmol). After stirring for about 4 h at ambient temperature, the reaction was concentrated under reduced pressure and then purified over silica gel (20 g) using DCM as the eluent to afford perfluorophenyl 2-cyanoacetate as a white solid (1.39 g, 94%): 1H NMR (400 MHz, CDCl3) δ 3.85 (s, 2H).
