Reaction Steps

To a suspension of AlCl3 (1.17 g; 8.79 mmol) in 1,2-dichloroethane (2 mL) was added acetyl chloride (0.55 g; 7.03 mmol). After 10 min stirring was added dropwise a solution of 5-fluoro-2-methoxyphenol (0.50 g; 3.52 mmol) in 1,2-dichloroethane (2 mL). The reaction mixture was stirred overnight at 40° C. The mixture was then poured on iced water and extracted with diethylether. The organic phases were combined, washed with brine, dried (Na2SO4) and concentrated to afford 582 mg (90%) of the title compound as an off-white solid.
