Reaction Steps

Nitric acid (0.326 mL, 7.29 mmol) 70% was added dropwise to a stirred solution of 2-fluoro-4-hydroxybenzonitrile (1 g, 7.29 mmol) in acetic acid (20 mL). The resulting solution was warmed to 40° C. for 24 hr. Solvent removed under reduced pressure to afford a yellow solid. Recrystallisation from EtOH (˜15 mL) afforded 2-fluoro-4-hydroxy-5-nitrobenzonitrile (401 mg, 2.202 mmol, 30.2% yield) as a yellow solid.
