Ethyl 6-chloroindole-2-carboxylate → (6-Chloro-1H-indol-2-yl)methanol

Participants

Reaction Steps

To 6-chloro-1H-indole-2-carboxylic acid ethyl ester (8.57 g) in THF at 0° C. was added lithium aluminum hydride solution (1M, in THF) dropwise and the reaction mixture was stirred for 3.5 h. The mixture was quenched with H2O, 15% NaOH, and H2O before it was filtered and rinsed with THF. Evaporation of the solvent gave 7.77 g of the crude (6-Chloro-1H-indol-2-yl)-methanol which was used directly in the next step.
