18.25 g of 3-bromobenzylamine hydrochloride, 17.39 g of sodium carbonate in aqueous solution (120 ml) and 1.90 g of tetrakis(triphenylphosphine)palladium (0) were added to toluene (240 ml) under a nitrogen atmosphere. The resulting solution was mixed with 10.00 g of phenylboric acid in ethanol (120 ml) at room temperature with stirring and refluxed under heating for 2 hours. After the reaction, the reaction solution was cooled to room temperature, poured into saturated aqueous sodium chloride and extracted with ethyl acetate, and the organic layer was dried over anhydrous magnesium sulfate and evaporated under reduced pressure for removal of the solvent to give 11.18 g of crude 3-phenylbenzylamine as a brown viscous liquid.
