실험 절차

A mixture of triethylsilane (3.1 mL), trifluoroacetic acid (0.88 mL) and dichloroethane (12 mL) at −15° C. was treated dropwise with a mixture of 3-formylpyridine-2-sulfonic acid phenyl[2-(trimethylsilanyl)ethoxymethyl]amide (0.55 g), (5-fluoro-2-methylindol-1-yl)acetic acid methyl ester (0.29 g) and dichloroethane (18 mL), and the resulting mixture was stirred at room temperature overnight. The mixture was concentrated under reduced pressure and the residue was dissolved in dichloromethane. The mixture was washed with saturated aqueous sodium hydrogen carbonate solution, dried over magnesium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with a mixture of dichloromethane, cyclohexane, ethyl acetate and methanol (9:1:0:0 to 0:0:9:1 by volume) to afford the title compound (0.20 g).
