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.
Fluorination of a benzene ring can be accomplished with Selectfluor, a reagent that contains a fluorine bonded to a positively charged nitrogen atom. Fluorination is a useful reaction because several common drugs, such as the cholesterol-lowering drug atorvastatin, contain a fluorine bonded to an aromatic ring. Assuming that fluorination is analogous to other examples of electrophilic aromatic substitution, draw a stepwise mechanism for the following reaction.
