実験手順

2-Ethyl-benzofuran-3-carbonyl chloride (0.444 mmol), prepared in step 2 of Example 21, was added under nitrogen to a suspension of 5-bromo-6-(1-methoxycarbonyl-2-phenyl-ethoxy)-naphthalen-2-ylmethyl-ammonium; chloride (0.200 g, 0.444 mmol), prepared in step 3 of Example 53, in 20 mL of methylene chloride. Triethylamine (0.124 mL, 0.888 mmol) was then added to the mixture. The reaction was stirred at room temperature for 18 h (overnight). The reaction was diluted with methylene chloride, extracted one time with 1N HCl and two times with 5% sodium bicarbonate. The organic layer was separated, dried (MgSO4) and the solvent removed under reduced pressure to give 2-(1-bromo-6-{[(2-ethyl-benzofuran-3-carbonyl)-amino]-methyl}-naphthalen-2-yloxy)-3-phenyl-propionic acid methyl ester (0.27 g, 100%) as a tan solid, mp 139-143° C.
