実験手順

A mixture of N-(2-Fluoro-4-iodophenyl)methanesulfonamide (13-3, 5 mmol) and palladium(II)acetate (0.15 nM, 0.034 g), 1,3-bisdiphenyl phosphinoprophan (0.3 mM, 0.124 g), thallium(I)acetate (5.5 mM, 1.450 g) and butylvinyl ether (10 mM, 1.3 mL) in DMF (10 mL) was heated at 95° C. for 19 h. The reaction mixture was cooled to room temperature, diluted with THF, treated with 10% HCl (10 mL) and stirred at room temperature. A mixture was diluted with EtOAc, washed with ammonium chloride solution three times and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel using EtOAc:hexanes as eluant to 3′-Fluoro-4′-(methylsulfonylamino)acetophenone (13-6, LJO-363).
