실험 절차

A mixture of 6-chloro-7-[(2-thienylsulfonyl)amino]-1H-indole-2-carboxamide (0.80 g), Lawesson's reagent (0.90 g) and tetrahydrofuran (15 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 (0.75 g, yield 91%) as yellow crystals. melting point 228-230° C. (decomposition).
