Trichloromethyl chloroformate (2.1 mL, 17.4 mmol) is added dropwise over ten minutes under a nitrogen atmosphere to a solution of 2-phenylphenol (3.0 g, 17.6 mmol) in 50 mL of methylene chloride at ice bath temperature. After the addition of trichloromethyl chloroformate, triethylamine (2.5 mL, 17.9 mmol) is added dropwise over a ten minute period and the reaction mixture is stirred at ice bath temperature for 2.5 hours. A solution of N-[[4-(2,2-dimethylpropyl)phenyl]methyl]heptylamine (4.8 g, 17.4 mmol) and triethylamine (2.5 mL, 17.9 mmol) in methylene chloride (15 mL) is added at ice bath temperature over a thirty minute period. Then the ice bath is removed and the reaction mixture is stirred overnight. The reaction mixture is washed with 1N HCl, 5% NaHCO3, dried over MgSO4 and the solvent removed in vacuo to give, after purification by high pressure liquid chromatography (hexane-methylene chloride) the title compound as a light brown oil (2.37 g, 29% of theory), MS/me, 471 (M+).
