Procedure

7-[(Cyclopropylmethyl)(2-thienylsulfonyl)amino]-1H-indole-2-carboxamide (264 mg), Lawesson's reagent (339 mg) and tetrahydrofuran (5 mL) were stirred at 60° C. for 2 hr. The reaction mixture was concentrated under reduced pressure, subjected to silica gel column chromatography, and eluted with an ethyl acetate-hexane (1:1) mixed solvent to give the title compound (243 mg, yield 88%) as an amorphous solid.
