실험 절차
A solution of ethyl ((1S)-5-{3-[4-(aminocarbonothioyl)-2-propylphenoxy]propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (0.5 g, 1.1 mmol) (Example 144) and 3-bromotetrahydro-2H-pyran-2-one (1.2 g, 6.6 mmol) (Example 151) in EtOH (anhydrous, 15 mL) was heated at 70° C. for 18 h. The reaction mixture was cooled to rt, and concentrated under reduced pressure. Purification by silica gel flash chromatography (EtOAc/hexane (v/v)=1:2) gave 0.17 g (29%) of the title compound as a light yellow oil. LC-MS: RT=4.52 min, (M+H)+:536.4.
