Reaction Steps

0.031 mL of 2-chloro-4-Iodotoluene, 39 mg of sodium hydrogen carbonate, 0.6 mL of ethanol, 0.3 mL of water and 11 mg of tetrakis(triphenylphosphine)palladium(0) were added to 1.6 mL of toluene solution containing 79 mg of tert-butyl 2-(benzamido)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate at room temperature, and the resulting mixture was heated to reflux for 8 hours. After the reaction mixture was cooled to room temperature, 11 mg of tetrakis(triphenylphosphine)palladium(9) was added and the resulting mixture was heated to reflux for 7 hours. After the reaction mixture was cooled to room temperature, ethyl acetate and water were added. The organic layer was separated and dried over anhydrous magnesium sulfate after washed with a saturated sodium chloride aqueous solution, and the solvent was evaporated under reduced pressure. The obtained residue was purified with silica gel column chromatography [PSQ100B (spherical) manufactured by Fuji Silysia Chemical Ltd., eluent; hexane:ethyl acetate=10:1] to obtain tert-butyl 2-(benzamido)-4-(3-chloro-4-methylphenyl)benzoate as white solid.
