실험 절차

A mixture of 1-(2-amino-4-chloro-5-methoxyphenyl)-3-methylpentan-2-ol (602 mg), tetrakis(triphenylphosphine)palladium (0) (135 mg), potassium carbonate (646 mg), 2-bromomesitylene (0.420 mL) and N,N-dimethylformamide (11.7 mL) was stirred at 160° C. for one hour under microwave irradiation. The reaction mixture was allowed to cool to ambient temperature. Water was added to the reaction mixture and this resulting mixture was extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over anhydrous sodium 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 (514 mg).
