PROCEDURE

实验过程

To a solution of Methyl (1RS, 2SR, 3RS)-3-[2-[(4-Carboxypyridin-3-yl)oxy]-4-methoxyphenyl]-1-(3,4-methylenedioxyphenyl)-5-(prop-1-yloxy)indane-2-carboxylate (90, 0.15 mmol) in isopropanol (2 mL) was added 1M aqueous NaOH (0.3 mL, 0.3 mmol). The resulting mixture was heated to reflux for 12 h, then concentrated under reduced pressure. The residue was partitioned between dilute HCl and ethyl acetate. The ethyl acetate extract was washed with water and dried (Mg2SO4). The solvent was removed in vacuo. The residue was purified by flash column chromatography (silica gel, 30% ethyl acetate/hexanes containing 5% of acetic acid) to afford the title compound (65 mg, 74%); m.p. 220-222° C. (dec.) (disodium salt).
