Versuchsvorschrift

A solution of 4-phenylbutylamine (610 μl, 3.86 mmol) and triethylamine (2.24 mL, 16.1 mmol) in 30 mL of methylene chloride was added under nitrogen dropwise to a solution of the carbonate prepared in Example 5 (2.0 g, 3.22 mmol) in 30 mL of methylene chloride at ice bath temperature. After the addition the cooling bath was removed and the reaction stirred at room temperature overnight. An additional 204 μl (1.29 mmol) of 4-phenylbutylamine and 180 μl (1.29 mmol) of triethylamine were added and the reaction stirred at room temperature for approximately 7 hours. The reaction was extracted one time with 1N HCl, multiple times with saturated Na2CO3, dried (MgSO4) and the solvent removed under reduced pressure to give 2.02 g of a crystalline solid. Purification of the solid on silica gel (230-400 mesh) using 5%-20% ethyl acetate-methylene chloride as the eluent gave 1.43 g (70%) of the title compounds as a white crystalline solid, mp 84°-86° C.
