실험 절차
To a 25 mL round bottom flask containing (S)-3-(5-chloro-2-methoxy-phenyl)-3-fluoro-1-hydroxymethyl-6-trifluoromethyl-1,3-dihydro-indol-2-one ((S)-IV) (0.397 g, 1.02 mmol) was added 5 mL anhydrous dichloromethane, triethylamine (0.204 g, 2.04 mmol), and 4-nitrophenyl chloroformate (0.246 g, 1.22 mmol). The reaction was allowed to stir overnight at room temperature, affording carbonic acid 3-(5-chloro-2-methoxy-phenyl)-3-fluoro-2-oxo-6-trifluoromethyl-2,3-dihydro-indol-1-ylmethyl ester 4-nitro-phenyl ester (VIII), after which 2-aminoethanol (0.186 g, 3.05 mmol) was added and the reaction was allowed to stir for an additional 24 hours. The solvent was removed in vacuo, and the crude residue was purified by column chromatography (silica gel; 1:1 Hex:EtOAc to 4:1 EtOAc:Hex) producing 0.250 g (51%) of the title compound. 1H NMR (CDCl3 400 MHz): δ=7.78 (s,1H), 7.51 (s, 1H), 7.33 (d, 2H, J=7 Hz), 7.22 (d, 1H, J=7 Hz), 6.74 (d, 1H, J=7 Hz), 5.88 (d, 1H, J=12 Hz), 5.83 (d, 1H, J=12 Hz), 3.75 (m, 2H), 3.50 (s, 3H), 3.39 (m, 2H, J=7 Hz).
