実験手順

A solution of ethyl ((1S)-5-{3-[4-(aminocarbonothioyl)-2-methoxyphenoxy]propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (Example 146, 90 mg, 0.2 mmol) and 2-chlorocyclohexanone (215 mg 1.6 mmol) in anhydrous EtOH (8 mL) was stirred at 70° C. for 48 h. The reaction was cooled, and the solvent was removed under reduced pressure. The residue was purified by silica gel flash chromatography (2:1 hexanes/ethyl acetate) to provide the title compound (62 mg, 58%) as clear oil. LC-MS: RT=4.08 min, (M+H)+ 522.5.
