실험 절차

To a stirred mixture of aluminium trichloride (2.5 kg) in dichloromethane (5000 ml) at room temperature was added propanoyl chloride (864 g) over a 5 minute period. The mixture was stirred for 45 minutes at room temperature and then a solution of 4-bromoanisole (875 g) in dichloromethane (1000 ml) was added over 15 minutes. The reaction was heated under reflux for 6 hours then cooled and stirred at room temperature overnight.
