Anhydrous diethylamine (0.11 moles) is added dropwise to a stirred solution of α,3-dichloro-4-cyclohexylphenylacetic 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,3-dichloro-4-cyclohexylphenylacetic acid, diethylammonium salt.
