Procedure
A mixture of 4-chloro-7-[methyl(2-thienylsulfonyl)amino]-1H-indole-2-carboxamide (0.54 g), Lawesson's reagent (0.59 g) and tetrahydrofuran (20 ml) was stirred at 60° C. for 3 hr. The reaction mixture was concentrated, toluene was added, and the resulting crystals were filtrated, washed with toluene, and dried to give the title compound (0.51 g, yield 87%) as yellow crystals. melting point >248° C. (decomposition).
