Reaction Steps

To a solution of methyl 4-(2-methylindol-3-yl)-4-oxobutyrate (2.0 g) in tetrahydrofuran (50 ml) was added a 1M solution of boran in tetrahydrofuran (16.5 ml) at 0° C. After stirred at 0° C. for 30 minutes, the mixture was poured into a mixture of ethyl acetate and brine. The organic layer was separated, washed with water and brine, and dried over magnesium sulfate. After evaporation of solvent, the residue was purified by column chromatography on silica gel (50 g) eluting with chloroform to give methyl 4-(2-methylindol-3-yl)butyrate (1.67 g) as a yellow oil.
