Reaction Steps

To a solution of N-[2-(4-amino-3-benzyloxy-phenyl)-ethyl]-2-(3,5-dibromo-4-methoxy-phenyl)-acetamide (0.836 g, 0.00152 mol) and p-toluenesulfonyl chloride (0.440 g, 0.00231 mol) in 40 mL of methylene chloride qas added 4 mL of pyridine. The reaction mixture was stirred for 54 h at room temperature, washed with 1N HCl, 1N NaOH solutions, dried over Na2SO4 and evaporated. A residue was crystallized from ethyl acetate-hexanes mixture. Yield 0.933 g (87%).
