Procedure

To a mixture of aluminum chloride (45.8 g, 0.343 mol) in methylene chloride (140 mL) was added propionyl chloride (10.85 mL, 124.9 mmol) all at once followed by 2-fluorophenol (5.57 mL, 62.44 mmol in 25 mL of methylene chloride with a 10 mL rinse). The mixture was gently refluxed 5 h, cooled to ambient temperature and poured onto ice. The phases were separated and the aqueous layer was extracted with methylene chloride. The combined organic layer was washed with aqueous bicarbonate and brine. The organic layer was dried over calcium sulfate and concentrated to give 11.43 g (82%) of 4-propionyl-2-fluorophenyl propionate as a clear tan oil which was used without characterization.
