Procedure
Epibromohydrin (0.64 ml, 7.5 mmole) was added to a stirred solution of 4-methoxyindole (1.0 g, 6.8 mmole) and sodium hydride (0.3 g, 7.8 mmole) in anhydrous DMF (20 ml), and the mixture was heated at 60° C. under nitrogen for two hours. Water (100 ml) was added and the product extracted into CH2Cl2 (3×25 ml). The combined organics were washed with water (25 ml), brine (25 ml) and dried over anhydrous sodium sulfate. Filtration and concentration in vacuo gave the crude product as a yellow colored oil (1.5 g). This was purified by flash silica gel chromatography (30% ethyl acetate in hexane) to afford the titled product as a light oil (1.27 g, 92% yield).
