Participants

Reaction Steps

To 1-fluoro-2-iodobenzene 0.11 g were added 2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl 9.5 mg, tris(dibenzylideneacetone)dipalladium(0) 3.7 mg, palladium acetate 0.90 mg, tert-butyl 2-amino-4-phenylbenzoate 54 mg, cesium carbonate 0.13 g and toluene 1.0 mL at room temperature, and it was heated and refluxed for 9 hours and 30 minutes. After the reaction mixture was cooled to room temperature, ethyl acetate and 1.0 mol/L hydrochloric acid were added to it. The organic layer was separated and collected, dried over anhydrous magnesium sulfate after washing with saturated sodium chloride aqueous solution, the solvent was removed under reduced pressure. The obtained residue was refined by silica gel column chromatography [Fuji SILYSIA Chemical Ltd., PSQ100B(spherical type), eluent];hexane:ethyl acetate=200:1] to give tert-butyl 2-(2-fluoroanilino)-4-phenylbenzoate 42 mg of a white solid.
