Procedure

n-Butanol (2.5 ml, 27 mmol) is added to a suspension of sodium hydride (50% in mineral oil; 1.3 g, 27 mmol) in DMF (5 ml) and the mixture is then heated to 80° C. for 1.0 hours when all the sodium hydride is consumed. A solution of 2,3-epoxypropyl benzyl ether (benzyl glycidylether*) (4.52 g, 27 mmol) in DMF (5 ml) is added slowly to the n-butoxide solution. The mixture is then heated to 80° C. for 16 hours, diluted with water and extracted with ether. The ether layer is dried and concentrated to give an oil which is distilled to provide the desired product (3.1 g), bp 125°-130°/0.8-0.5 mm.
