Reaction Steps

To a solution of cumene (42 g, 350 mmol) and aluminum chloride (56.0 g, 420 mmol) in dichloromethane (500 mL) was added bromoacetylbromide (33.5 mL, 385 mmol) at −40° C. for 40 minutes, and the mixture was stirred until it was warmed to −10° C. for 2 hours. The reaction solution was poured into ice-cold water to separate the organic layer. The organic layer was washed with a saturated sodium hydrogen carbonate solution and a saturated brine, and then was dried over sodium sulfate. The solvent was distilled off under reduced pressure to obtain 84 g (yield 99%) of the title compound. Oily matter.
