Cesium carbonate → Ethyl 2-(7-(4-(Cyclohexylmethyl)-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetate

Participants

Reaction Steps

To a stirred reaction mixture of ethyl 2-(7-hydroxy-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetate (40 mg, 0.15 mmol) and cesium carbonate (75 mg, 0.23 mmol) in DMF (1 mL) was added 4-(bromomethyl)-1-(cyclohexylmethyl)-2-(trifluoromethyl)benzene (78 mg, 0.23 mmol). The reaction mixture was stirred at room temperature for 1 h. The solid was filtered and washed with ethyl acetate. The combined filtrate was concentrated, and the residue was purified by preparative TLC to give the title compound (40 mg) as an oil.
