Reaction Conditions

Reaction Steps

To a solution of 4-phenyl-2-chloro-1-trifluoromethylsulfonyloxybenzene (35 g) in dimethylformamide (300 ml) are added palladium acetate (1.17 g), 1,3-bis(diphenylphosphino)propane (4.29 g), ethanol (91.5 ml) and triethylamine (29.0 ml) under carbon monooxide atmosphere, and the mixture is heated with stirring at 80-90° C. for 6 hours. To the reaction solution is added water, and further added a small amount of n-hexane. The mixture is extracted with ethyl acetate, and the ethyl acetate layer is washed with water, dried, and the residue is purified by silica gel column chromatography (solvent; n-hexane→ethyl acetate:n-hexane=1:100) to give ethyl 4-phenyl-2-chlorobenzoate (20.9 g) as colorless oil.
