Procedure

To a solution of triphenylphosphine oxide (1.98 g) in acetonitrile (30 mL) was slowly added trifluoromethanesulfonic anhydride (0.60 mL) at 0° C., and the mixture was stirred for 10 min. N-{[8-(Benzylthio)-1,4-dioxaspiro[4.5]dec-8-yl]methyl}-7-[methyl(2-thienylsulfonyl)amino]-1H-indole-2-carboxamide (1.45 g) and dimethylsulfide (0.52 mL) were added, and the reaction mixture was stirred at 0° C. for 30 min. Saturated aqueous sodium hydrogencarbonate was added, and the precipitated solid was collected by filtration, and washed with water. The obtained solid was washed with ethyl acetate, and dried to give the title compound (0.75 g, yield 63%) as colorless crystals. melting point 224-225° C.
