2-Chlorocyclohexanone → ethyl((1S)-5-{3-[2-propyl-4-(4,5,6,7-tetrahydro-1,3-benzothiazol-2-yl)phenoxy]propoxy}-2,3-dihydro-1h-inden-1-yl)acetate

Participants

Reaction Steps

A solution of 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 2-chlorocyclohexanone (239 mg 1.8 mmol) in EtOH (anhydrous, 8 mL) was stirred at 70° C. for 48 h. The reaction mixture was cooled to rt, and then concentrated under reduced pressure. Purification by silica gel flash chromatography (EtOAc/hexane (v/v) 1:2) gave 45 mg (43%) of the title compound as a clear oil. LC-MS: RT=4.69 min; (M+H)+ 534.3.
