Conditions

Temperature: 70 °C

Procedure

A mixture of 7-[[(2-methoxyphenyl)sulfonyl](methyl)amino]-1H-indole-2-carboxamide (2.82 g), Lawesson's reagent (1.6 g) and tetrahydrofuran (250 mL) was stirred at 70° C. for 3 hr. The reaction solution was concentrated under reduced pressure, and the obtained oil was crystallized from ethyl acetate-hexane to give the title compound (2.3 g, yield: 78%) as pale-yellow crystals.
