Anhydrous diethylamine (0.11 moles) is added dropwise to a stirred solution of 2'-chloro-4-biphenylylglycolic acid (0.10 moles) in 100 ml. of n-hexane at 0°C. The precipitated diethylammonium salt is collected on a filter washed with n-hexane and dried in a vacuum desiccator to obtain 2'-chloro-4-biphenylylglycolic acid, diethylammonium salt.
