Reaction Steps

In a 4 mL vial were placed ethyl 2-(7-hydroxy-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetate (64.8 mg, 0.250 mmol), cesium carbonate (81 mg, 0.250 mmol), and 4-(4-(bromomethyl)phenyl)-1,2,3-thiadiazole (63.8 mg, 0.250 mmol). DMA (1 mL) was added and the reaction was stirred at room temperature overnight. The solid was removed by filtration and rinsed with EtOAc. The filtrate was concentrated under reduced pressure and the residue was purified by silica gel column chromatography to give the title compound (42.7 mg). LCMS m/z=434.2 [M+H]+.
