Reaction Steps

To a solution of 6-(methylthio)-1-(phenylsulfonyl)-1H-indole (890 mg, 2.93 mmol) in anhydrous THF (10 mL) at 0° C. under nitrogen was added n-BuLi (5.86 mL, 14.65 mmol, 2.5 M). After stirring for 30 min, isobutyraldehyde (1.05 g, 14.65 mmol) was added. The reaction mixture was stirred at 0° C. for 1 h and quenched with sat. aq NH4Cl (10 mL) at 0° C. and extracted with EtOAc (20 mL×3). The combined organic layers were dried over anhydrous sodium sulfate, filtered, concentrated and purified by column chromatography on silica gel eluted with (petroleum ether/EtOAc 20:1) to give 2-methyl-1-(6-(methylthio)-1H-indol-2-yl)propan-1-one (440 mg, 64.28% yield) as a colorless oil.
