Procedure
To a solution of 2-fluoro-6-chlorobenzonitrile (10.35 g, 66.5 mmol) in 1,2-dimethoxyethane (50 mL) at 0° C. was added potassium t-butoxide (9.06 g, 80.7 mmol). The mixture was slowly allowed to warm to room temperature over 3 h. The reaction was poured into water and extracted with ether (3 times). The organic layers were washed with brine, dried (MgSO4) and concentrated to afford 13.52 g (97%) of 2-[(1,1-dimethylethyl)oxy]-6-chlorobenzonitrile as a pale yellow oil.
