Procedure

14.4 g (0.05 mole) β-chloro-β,β-diphenyl-propionic acid ethyl ester (prepared from β-hydroxy-β,β-diphenyl-propionic acid ethyl ester, Ber. 40, 4538, by treatment with phosphorus pentachloride) are heated in 100 ml acetonitrile with 10 g imidazole at boiling temperature for 16 hours. The solvent is distilled off in a vacuum, the residue treated with 50 ml of water and extracted with methylene chloride. After drying, the solvent is distilled off in a vacuum. The β-imidazolyl-β,β-diphenyl-propionic acid ethyl ester is thus obtained in the form of crystals of m.p. 75° C.
