Versuchsvorschrift

A mixture of trifluoromethanesulfonic anhydride (100 mg), triphenylphosphine oxide (95 mg) and dichloromethane (5 mL) was stirred at 0° C. for 10 min. A solution of N-[2-(benzylthio)-3-(1,1-dioxidothiomorpholino)propyl]-5-(2-methoxyethoxy)-7-[(pyridin-2-ylsulfonyl)amino]-1H-indole-2-carboxamide (210 mg) and thioanisole (80 mg) in dichloromethane (40 mL) was added dropwise to the reaction mixture under ice-cooling, and the mixture was stirred for 2 hr under ice-cooling. The reaction mixture was added dropwise to a mixture of trifluoromethanesulfonic anhydride (100 mg), triphenylphosphine oxide (95 mg) and dichloromethane (2 mL) under ice-cooling, and the mixture was stirred at room temperature for 15 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4), and concentrated. The residue was subjected to silica gel column chromatography, and eluted with hexane-ethyl acetate (2:3-5:95, volume ratio) to give the title compound (80 mg, yield 44%) as colorless crystals. The crystals were recrystallized from acetone-hexane to give colorless prism crystals. melting point 218-219° C.
