실험 절차

A solution of 7-[(2-thienylsulfonyl)amino]-1H-indole-2-carbothioamide (4.3 g), ethyl but-2-ynoate (3.2 mL) and tributylphosphine (3.2 mL) in tetrahydrofuran (40 mL)-toluene (40 mL) was stirred at room temperature for 2 days. ethyl but-2-ynoate (1.6 mL) was added to the reaction solution again, and the mixture was stirred at 60° C. for 2 hr. The reaction solution was concentrated under reduced pressure, and the obtained residue was subjected to silica gel column chromatography (ethyl acetate:hexane=2:8-4:6) to give the title compound (1.6 g, yield: 28%) as a pale-brown oil.
