合成路线1
1) The reaction of p-fluorothiophenol (I) with p-chloronitrobenzene (II) in 50% aqueous ethanol in the presence of sodium carbonate gives p-fluorophenyl-p-nitrophenyl sulfide (III), which is then oxidized with 30% aqueous hydrogen peroxide in glacial acetic acid to give the corresponding sulfone (IV). The catalytic reduction of the sulfone (IV) with Raney Nickel in p-dioxane affords p-(p-fluorophenylsulfonyl)aniline (V), which is then acetylated with acetic anhydride in tetrahydrofuran to give title compound.
