実験手順

6-Hydroxy-1-oxo-3-phenyl-1H-indene-2-carboxylic acid cyclohexylamide (141 mg, 0.41 mmol) obtained in Step 3 was dissolved in tetrahydropyran/benzene (3 mL/2 mL), and 4-(2-hydroxyethyl)morpholine (99 μl, 0.82 mmol) and triphenylphosphine (215 mg, 0.82 mmol) were added thereto. Then, diisopropyl azodicarboxilate (149 μl, 0.82 mmol) was added slowly thereto at 0° C., and stirred for 2 hrs at RT. The resulting mixture washed with saturated saline and extracted with ethyl acetate. The organic layer was separated, dried over anhydrous MgSO4 and concentrated under a reduced pressure. The resulting residue was purified by flash chromatography to obtain 165 mg of the titled compound (yield: 88.3%).
