A solution of 2-fluoro-6-methoxybenzaldoxime (714 mg, 4.2 mmol) in Ac2O (3.6 mL) is heated at reflux for 4 hr. The reaction is cooled to r.t. and the volatiles are stripped off to give a beige solid, which is dried at 50° C. in a vacuum oven to give 2-fluoro-6-methoxybenzonitrile (635 mg, 84%). 1H NMR (DMSO) δ7.8-7.7 (1H, m), 7.14-7.07 (2H, m),3.95 (3H, s).
