실험 절차

A solution of (S)-3-(5-chloro-2-methoxy-phenyl)-3-fluoro-2-oxo-6-trifluoromethyl-2,3-dihydro-indole-1-carboxylic acid 2-(di-tert-butoxy-phosphoryloxy)-propyl ester ((S)-VII, n=2) (540 mg, 0.82 mmol) in dichloromethane (30 mL) was stirred with trifluoroacetic acid (0.6 mL) at room temperature for 3 hours. LC-MS indicated the completion of the reaction. After removal of the solvent the residue was dissolved in methanol and the crude product was purified by prep. HPLC, affording the title compound 255 mg (57%) as white solid after lyophilization. 1H NMR (CDCl3, 500 MHz) δ 8.27 (s, 1H), 7.73 (d, 1H), 7.42 (d, 1H), 7.32 (d, 1H), 7.27 (d, 1H), 6.75 (d, 1H), 4.50 (b, 6H, containing some H2O as solvate), 4.54 (m, 2H), 4.17 (b, 2H), 3.49 (s, 3H), 2.1 (m, 2H); MS (m/e) 539.92 (M+−1); LC-MS, 542 (MH+, 98.5%); 31P NMR (CDCl3, 500 MHz) δ 2.03; 19F NMR (CDCl3, 500 MHz) δ−63.4, 153.8; Anal. Calcd. for C20H17ClF4NO8P: C=44.34%, H=3.16%, N=2.58%; Found: C=44.01%, H=3.11%, N=2.45%.
