Water → 2-bromo-1-(4-methoxyphenyl)-3-(methylthio)-1H-indole

Participants

Reaction Steps

NBS (529 mg, 2.97 mmol) was added to a cooled (0° C.) solution of 1-(4-methoxyphenyl)-3-(methylthio)-1H-indole (800 mg, 2.97 mmol) in 10 ml of DMF. The temperature was allowed to warm to RT and the mixture was stirred at RT for 30 min. Water and DCM were added and the phases were separated. After evaporation of the solvents, the residue was purified by flash chromatography with heptane/EtAc 20:1 to provide 2-bromo-1-(4-methoxyphenyl)-3-(methylthio)-1H-indole in 66% yield. ES/MS m/z: 348.04, 350.01 (M+H).
