실험 절차

A mixture of 2-[1-bromo-6-({[5-(3,5-dichloro-phenoxy)-furan-2-carbonyl]-amino}-methyl)-naphthalen-2-yloxy]-3-phenyl-propionic acid methyl ester (0.34 g, 0.508 mmol), prepared in the previous step, 1N NaOH (1.50 mL, 1.5 mmol), 5 mL of water and 50 mL of methanol was stirred under nitrogen at room temperature for 18 h (overnight). The methanol was removed under reduced pressure. The solid that formed was collected by filtration and identified as the sodium salt salt of 2-[1-bromo-6-({[5-(3,5-dichloro-phenoxy)-furan-2-carbonyl]-amino}-methyl)-naphthalen-2-yloxy]-3-phenyl-propionic acid (0.1537 g, 46%). The clear filtrate was acidified with 1N HCl. The solid that precipitated was collected by filtration and dried under reduced pressure to give the title compound (0.0905 g, 27%) as a white solid, mp 86-100° C.
