Reaction Steps

7-Hydroxyindole (1.0 equivalents) is dissolved in dry, degassed acetone. EtBr (5.0 equivalents) and Cs2CO3 (2.5 equivalents) are added, and the resulting solution is stirred for 18 hours. The reaction mixture is filtered through a Celite plug. The solvent is evaporated, and the product is purified by flash chromatography (MeOH:CH2Cl2, 5:95) to yield the title compound.
