2-(3-Cyano-4-fluorophenyl)acetic acid → Methyl 2-(3-cyano-4-fluorophenyl)acetate

Participants

Reaction Steps

A solution of crude (3-cyano-4-fluorophenyl)acetic acid (980 mg, 5.6 mmol) in methanol (10 mL) was added 5 M HCl/MeOH (10 mL). The reaction was stirred at ambient temperature overnight and concentrated. The residue was purified with preparative TLC to afford methyl (3-cyano-4-fluorophenyl)acetate. 1H-NMR (300 MHz, CDCl3) δ ppm 7.49˜7.55 (m, 2H), 7.17 (t, J=8.2 Hz, 1H), 3.71 (s, 3H), 3.63 (s, 2H).
