Reaction Steps

Ethyl ((1S)-5-{3-[4-(aminocarbonothioyl)-2-methoxyphenoxy]propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (90 mg, 0.2 mmol) (Example 146) and 1-bromo-2-butanone (36.7 mg, 0.24 mmol) were dissolved in EtOH (anhydrous, 8 mL) and stirred at 70° C. for 6 h. The reaction was cooled to rt, and concentrated under reduced pressure. Purification by silica gel flash chromatography (EtOAc:hexane (v/v)=1:2) gave 50 mg (51%) of the title compound as a clear oil. LC-MS: RT=4.07 min; (M+H)+ 496.2.
