실험 절차

To a solution of 5.72 g of 5-cyano-N-[2-(3-hydroxy-2′-methanesulfonylbiphenyl-4-yl)ethyl]-2-methoxybenzenesulfonamide in 57 mL of N,N-dimethylformamide were added 2.46 mL of N,N-diisopropylethylamine and 1.37 mL of ethyl bromoacetate. After being stirred at 50° C. for 15 hours, and the reaction mixture was poured into 100 mL of water, and extracted with a mixture of 150 mL of ethyl acetate and 20 mL of toluene. The organic layer was washed with water and brine, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under reduced pressure, and the residue was purified by column chromatography on aminopropylated silica gel (eluent: ethyl acetate-hexane) to give 2.96 g of ethyl[4-[2-(5-cyano-2-methoxybenzenesulfonylamino)ethyl]-2′-methanesulfonylbiphenyl-3-yloxy]acetate as an amorphous material.
