Procedure: Into a 3 neck flask, equipped with water cooler, were added 43.8 mL (0.22 mol) of diethyladipate and 220 mL THF. 16.3 g (0.24 mol, 1.1 equivalents) of NaOEt were added in small portions, at 20° C., and the reaction mixture was stirred at 60° C. for 16 hours. After cooling to 20° C., 48.6 g (0.20 mol) of 2-phenyl-benzyl bromide was added dropwise. The reaction mixture was stirred at 60° C., for 16 hours, to give 2-(2-phenyl-benzyl) adipic acid diethylester as a viscous oil, in a yield of 92%. After cooling to 20° C. The reaction mixture was stirred at 60° C., for 16 hours

Procedure: 188 g (1 mol) of diethyl ethylmalonate dissolved in 100 cm3 of H2O-free EtOH are added dropwise at room temperature to 23 g (1 mol) of sodium in 400 cm3 of H2O-free EtOH. 247 g (1 mol) of 2-phenylbenzyl bromide in 300 cm3 of H2O-free EtOH were subsequently added dropwise, and the mixture was refluxed for 3 hours. 170 g (3 mol) of KOH dissolved in 300 cm3 of H2O were added at room temperature, and the mixture was refluxed for a further 4 hours. The solvent was removed in vacuo, H2O was added to the residue until the latter had dissolved completely, and the mixture was subsequently acidified to pH 1 by means of concentrated aqueous HCl. The precipitate which formed was filtered off with suction, dried and heated at 130° C. for 1 hour, giving 236 g (93%) of 13 as a viscous oil. the mixture was refluxed for 3 hours were added at room temperature the mixture was refluxed for a further 4 hours The solvent was removed in vacuo, H2O was added to the residue until the latter had dissolved completely The precipitate which formed was filtered off with suction dried
