Sodium Chloride → 1-(2-chloro-5-methoxyphenyl)ethanone

To a solution of SELECTFLUOR™ (5.0 g, 14.1 mmol) and sodium chloride (825 mg, 14.1 mmol) in acetonitrile (200 ml), under nitrogen, was added 1-(3-methoxyphenyl)ethanone (1.94 ml, 14.1 mmol) and the reaction mixture was stirred at room temperature for 5 days. To the mixture was added distilled water (200 ml) and the solution was extracted with dichloromethane (2×100 ml). The combined extracts were dried (MgSO4) and concentrated in vacuo. The residue was purified by column chromatography (silica) with gradient elution, ethyl acetate:cyclohexane [5:95 to 10:90]. The appropriate fractions were combined and concentrated to give the title compound (1.12 g).
