Reaction Steps

Ethyl ((1S)-5-{3-[4-(aminocarbonothioyl)-2-propylphenoxy]propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (90 mg, 0.2 mmol) (Example 144) and 3-chloro-2,4(3H, 5H)-furandione (106 mg, 0.8 mmol) were dissolved in EtOH (anhydrous, 8 mL), and the mixture was heated at 70° C. for 18 h. The reaction was cooled to rt, and then concentrated under reduced pressure. Purification by silica gel flash chromatography (EtOAc:hexane (v/v)=1:1) gave 38 mg (33%) of the title compound as a clear oil. LC-MS: RT=4.38 min; (M+H)+ 582.3.
