Ibufenac, a para-disubstituted arene with the structureHO2CCH2C6H4CH2CH(CH3)2 , is a much more potent analgesic thanaspirin, but it was never sold commercially because it caused livertoxicity in some clinical trials. Devise a synthesis of ibufenac frombenzene and organic halides having fewer than five carbons.
