Preparation of chlorodiphenylacetic acid
20 g of hydroxy(diphenyl)acetic acid, are gently warmed with an 20 g of phosphorus oxychloride until the acid goes into solution and a red color begins to make its appearance. The reaction mixture is allowed to cool and the crystalline crude mass thus obtained shaken with a 1000 ml of cold water for 1-2 hours until the chlorodiphenylacetic acid has become solid. Chlorodiphenylacetic is then collected, washed with water, dried, and recrystallized from a mixture of benzene and ligroin forming colorless rhombic tablets with melting point 118-119 ° C with decomposition. Yield 65 %.
