The precursor 4-fluoro-3-(trifluoromethylsulfonyl)benzenesulfonamide (VII) can be prepared by the following methods:
Condensation of 2-fluorobenzenethiol (X) with iodotriluoromethane in the presence of triethylamine and methyl viologen (1,1’-dimethyl-4,4’-bipyridinium dichloide) yields the trifluoromethyl sulfide (XI), which is oxidized to sulfone (XII) by means of NaIO4 and catalytic RuCl3 (1, 2). Subsequent chlorosulfonation of (XII) with ClSO3H affords the acid chloride (XIII), which is finally converted to the target sulfonamide (VII) upon quenching with ammonium hydroxide in cold isopropanol (1-3). Scheme 2.
In an improved method, treatment of bis(o-nitro-phenyl)disulfide (XIV) with potassium trifluoroacetate in sulfolane at 180-230 °C provides the trifluoromethyl sulide (XV), which is oxidized to the corresponding sulfone derivative (XVI) using periodic acid and a catalytic amount of CrO3. Finally, compound (XIV) is submitted to nitro group displacement with dried potassium fluoride and tetraphenylphosphonium bromide in hot DMSO (3). Scheme 2.
