実験手順

To an ethanol (2.0 mL) solution of (E)-5-[(1R,2S)-2-hydroxyindan-1-ylamino]-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)benzylidene]valeric acid ethyl ester (120 mg), 2N sodium hydroxide solution (1.0 mL) was added. After carrying out heat-refluxing of the reaction solution for 30 minutes and confirming disappearance of the starting materials, water and ethyl acetate were added to the reaction solution, and the organic layer was partitioned. After the obtained organic layer was washed with a saturated saline solution, it was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography (Carrier: Chromatorex™ NH, elution solvent: heptane-ethyl acetate=1:1->ethyl acetate->ethyl acetate:ethanol=10:1), and 78.9 mg of the title compound was obtained.
