Procedure

Water (0.60 mL), 2-methylphenylboronic acid (0.029 g), sodium carbonate (0.047 g), and bis(triphenylphosphine)palladium(II) dichloride (2.5 mg) were added to an ethylene glycol dimethyl ether (2.0 mL) solution of tert-butyl 2-(2-(benzyloxy)-5-(piperidin-1-yl)benzamido)-4-bromobenzoate (0.10 g), followed by heating to reflux under a nitrogen atmosphere for 2 hours. The reaction mixture was cooled to room temperature, and water and ethyl acetate were added thereto. The organic layer was separated, washed with a saturated aqueous solution of sodium chloride, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography [eluent: 99-91% hexane/ethyl acetate] to obtain 0.10 g of tert-butyl 2-(2-(benzyloxy)-5-(piperidin-1-yl)benzamido)-4-(2-methylphenyl)benzoate.
