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