Reaction Steps

Epibromohydrin (1.0 g, 7.6 mmole) was added to a stirred solution of 2-methylbenzimidazole (1.0 g, 7.6 mmole) and sodium hydride (0.3 g, 7.6 mmole) in anhydrous DMF (20 ml), and the mixture was heated at 60° C. under nitrogen for 0.5 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 light yellow colored oil (1.4 g). This was purified by flash silica gel chromatography (10% methanol in CH2Cl2) to afford the titled product as a light oil (0.64 g, 45% yield).
