1,5-Dibromopentane → 5-(2-(5-Methyl-2-phenyloxazol-4-yl)ethoxy)pentylbromide

Participants

Reaction Steps

The mixture of 2-(5-methyl-2-phenyloxazol-4-yl)ethanol (2.03 g), 1,5-dibromopentane (4.09 ml), 50% NaOH (4.0 ml) and tributylammonium bromide (0.1 g) was stirred at room temperature overnight. The reaction mixture was dilluted with ether, washed by water and an aqueous saturated solution of sodium chloride sucessively, dried over anhydrous magnesium sulfate and concentrated. The residue was purified with silica gel column chromatography (hexane:ethyl acetate=10:1→4:1) to obtain the title compound (3.45 g) having the following physical data.
