Reaction Steps

5-(5-Methyl-2-phenyloxazol-4-yl)-1-pentanol (2.9 g) was dissolved in 62 ml of dry ether, and 8.4 g of carbon tetrabromide was added. To the mixture was added gradually 6.6 g of triphenylphosphine under ice-cooling. The mixture was then stirred for 2.5 hours at room temperature, filtrated to remove insolubles and the filtrate was concentrated. The residue was purified by silica gel column chromatography (Wakogel® C-200, n-hexane:ethyl acetate=10:1) to provide 2.61 g of the objective compound as yellowish oil.
