Reaction Steps

A mixture of 7-(1-methylethoxy)-5-[4-(methylsulfonyl)phenoxy]-1H-indole-2-carbothioamide (857 mg), ethyl 2-butynoate (0.6 mL), tributylphosphine (0.6 mL), tetrahydrofuran (10 mL) and toluene (15 mL) was stirred at 60° C. for 1.5 h. The mixture was cooled to room temperature and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane=1/99 to 40/60, volume ratio) to give the title compound (381 mg, 41%) as a yellow amorphous solid. MS 517 (MH+).
