To a pre-cooled (ice bath) solution of N-(2-nitrobenzenesulfonyl)-N-(2-pyridinylmethyl)-N′-(5,6,7,8-tetrahydro-8-quinolinyl)-1,4-benzenedimethanamine (201 mg, 0.37 mmol) and triethylamine (80 μl, 0.55 mmol) in anhydrous CH2Cl2 (4 mL) was added a solution of benzoylchloride (54 μl, 0.46 mmol) in anhydrous CH2Cl2 (0.5 mL) and the reaction mixture was allowed to stir at room temperature for 18 hours and then concentrated. The residue was diluted with ethylacetate (300 mL), washed with sat. aqueous NaHCO3 then brine, dried (Na2SO4) and evaporated. The residue was purified by column chromatography on silica gel (1.5×20 cm, 50:50 EtOAc/CH2Cl2) to give the desired amide (203 mg, 85%) as a yellow oil.
