Ibufenac, a para-disubstituted arene with the structure HO2CCH2C6H4CH2CH(CH3)2, is a much more potent analgesic than aspirin, but it was never sold commercially because it caused liver toxicity in some clinical trials. Devise a synthesis of ibufenac from benzene and organic halides having fewer than five carbons.
