Conditions

Temperature
70 °C

Procedure

n-Octyl bromide (0.102 mol) is added to a solution of 4-(4-hydroxyphenyl)benzoic acid (0.102 mol) and 2.5 N sodium hydroxide (0.102 mol) and the mixture stirred at 70° C. for a period of 18 hours. The reaction mixture is allowed to cool and then acidified to pH 3 and partitioned between ethyl acetate and water. The organic phase is washed with water and brine and the solvent then removed to obtain the 4'-n-octyloxy-[1,1'-biphenyl]-4-ylcarboxylic acid, C21H23O3, M.W. 326.4
