Reaction Steps

To a solution of ethyl 2-(1-acetyl-2-(bromomethyl)-1H-indol-3-yl)acetate (I-4A, 640 mg, 1.9 mmol) in acetone (10 ml) was added potassium ethanethioate (1.3 g, 11.2 mmol). The solution was heated at reflux for 1 hour. The solution was cooled and then diluted with EtOAc (50 ml) and washed with NaHCO3 (aq) (2×25 ml). The organic layer was dried with Na2SO4, filtered and concentrated. The crude product was introduced to a silica gel loading column and purified by column chromatography (10-30 EtOAc/hexanes) to get 533 mg (1.6 mmol, 84%) product. MS (m/z) 334 [M+H]+.
