实验过程

To a suspension of LiAlH4 (2.0 g, 0.052 mol) in 50 mL of dry tetrahydrofuran was added dropwise a solution of methyl 1-methylindole-3-acetate (5.25 g, 0.026 mol) in 70 mL of dry tetrahyqrofuran at -10° C. under Ar. The mixture was refluxed for 1 h and then it was cooled at 0° C. and quenched by the sequential addition of 2 mL of H2O, 2 mL of 15% aqueous NaOH and finally 6 mL of H2O. The resulting slurry was filtered and the filter cake was washed with additional tetrahydrofuran. Evaporation of the filtrate gave the product (40 g, 89%) as an oil which was used without further purification.
