Reaction Steps

A mixture of 7-[(2-thienylsulfonyl)amino]-1H-indole-2-carboxamide (0.66 g), Lawesson's reagent (0.88 g) and tetrahydrofuran (20 mL) was stirred at 40° C. overnight. The reaction mixture was concentrated, the obtained residue was subjected to silica gel column chromatography, and the title compound (0.61 g, yield 86%) was obtained as yellow crystals from a fraction eluted with tetrahydrofuran-hexane (3:2, volume ratio). melting point 249-250° C. (decomposition).
