実験手順

To 400 ml ethanol is added 21.5 g of 4-hydroxy-4'-nitrobiphenyl, and the mixture is heated to reflux. A solution of 7.1 g KOH in 30 ml of water is added dropwise at reflux temperatures. After complete addition, 18 g of 5-bromo-1-pentene is added and the reaction medium is heated at reflux temperarure for about 15 hours. Ethanol is removed under vacuum from the cooled mixture, and the solid residue is slurried with water in a blender,filtered, washed with water, and air dried. The product then is recrystallized from 90/10 hexane/toluene, mp 74°-76° C.
