実験手順

2.0 g of 2-(4-chlorophenyl)-3-methylbutanol in 10 ml of a 20% mixture of dimethylformamide and toluene was added over a 5 minute period to sodium hydride (0.8 g, 50% in oil) in 20 ml of toluene at 110°-120° C, and the mixture was stirred for 15 minutes. 3.0 g of 3-phenoxybenzyl bromide in 15 ml of toluene was then added over a 15 minute period and the mixture was gently refluxed for 2 hours, then was cooled and 10 ml of mineral spirits was added. The mixture was poured into ice/hydrochloric acid, extracted with ether, washed with sodium bicarbonate solution and dried (MgSO4). The solvent was removed to give an orange oil, which was chromatographed on silica gel using 1:1 methylene dichloride:hexane as eluent to give 1.
