A mixture of (2S,3S)-3-(2,3-dihydro-1H-indol-1-yl)-3-(3-fluorophenyl)propane-1,2-diol (2.00 g, 6.96 mmol) and activated manganese dioxide (20.0 g, 230 mmol) in dichloromethane (30 mL) was stirred at 20° C. for 3 hours. The mixture was diluted with ethyl acetate (15 mL), filtered through a pad of silica gel, and concentrated. The crude product was purified by Biotage chromatography (FlasH40i, silica, 0-70% EtOAc/hexane) to give 1.40 g (71%) of (2S,3S)-3-(3-fluorophenyl)-3-(1H-indol-1-yl)propane-1,2-diol as a colorless oil. MS (ESI) m/z 286.0 ([M+H]+). HRMS: calcd for C17H16FNO2+H+, 286.1238; found (ESI, [M+H]+), 286.1239.
