반응 단계
A solution of 2-carbomethoxy-6-methylsulfonylindole (750 mg, 2.8 mmol), in 10 mL hexafluoroisopropanol was treated with 2,4-difluorothiophenol (7.5 mmol) followed by addition of PIFA (5.6 mmol). The dark colored solution was stirred overnight then partitioned between methylene chloride and water. After concentration of the methylene chloride layer to 20 mL the product was precipitated by addition of 30 mL hexane. An 88% yield of 3-(2,4-difluoro-phenylsulfanyl)-6-methanesulfonyl-1H-indole-2-carboxylic acid methyl ester was obtained.
