Procedure

A mixture of 7-(methyl{[2-(trifluoromethyl)phenyl]sulfonyl}amino)-1H-indole-2-carboxamide (2.6 g), Lawesson's reagent (1.3 g) and tetrahydrofuran (50 mL) was stirred at 60° C. for 3 hr. The reaction solution was concentrated under reduced pressure, and the obtained oil was crystallized from toluene to give the title compound (2.65 g, yield: 100%) as pale-yellow crystals.
