Reaction Steps

To a solution of ethyl 2-(7-hydroxy-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetate (50.0 mg, 0.193 mmol) and 4-(chloromethyl)-1-cyclopentyl-2-(trifluoromethyl)benzene (152.0 mg, 0.578 mmol) in DMF (3 mL) was added cesium carbonate (75.0 mg, 0.231 mmol). The mixture was stirred at room temperature overnight, filtered through Celite®, and concentrated under reduced pressure. The residue was purified by HPLC to give the title compound as a light pink oil (38.7 mg). LCMS m/z=486.5 [M+H]+.
