Reaction Conditions

Reaction Steps

To a suspension of methyl 3-{[2-(2-hydroxy-3,3-dimethylbutyl)-4-methoxyphenylamino]methyl}benzoate (200 mg), 2-bromomesitylene (0.097 mL) and potassium carbonate (148 mg) in N,N-dimethylformamide (5 mL) was added tetrakis(triphenylphosphine)palladium (0) (31.1 mg) at room temperature, and this resulting mixture was stirred at 150° C. for 2 hours under an argon atmosphere. The reaction mixture was cooled to room temperature, diluted with water and extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluting solvent: ethyl acetate-hexane) to obtain the title compound (127 mg).
