실험 절차

7-[4-(4-Chloro-phenyl)-piperazin-1-ylmethyl]-10-oxo-1,3,4,9,10,10a-hexahydro-2,4a,5,9-tetraaza-phenanthrene-2-carboxylic acid tert-butyl ester (250 mg, 0.487 mmol) was dissolved in dichloromethane (5 mL) and trifluoroacetic acid (3 mL) was added while stirring at room temperature. The reaction was stirred for 16 h and concentrated to a residue. The residue was dissolved in DMF and purified via HPLC (55-90% acetonitrile in water, ammonium bicarbonate buffer). The fractions were combined and concentrated until a white solid precipitated. The precipitate was filtered off and dried in vacuum to afford the title compound (17.8 mg, 8.8%) as a white solid. 1H NMR (DMSO-d6) δ (ppm): 10.68 (s, 1H), 7.70 (d, J=2.0 Hz, 1H), 7.14-7.30 (m, 2H), 7.03 (d, J=2.0 Hz, 1H), 6.92 (d, J=9.1 Hz, 2H), 4.33 (d, J=11.4 Hz, 1H), 3.97 (dd, J=11.0, 3.4 Hz, 1H), 3.45 (dd, J=12.5, 2.9 Hz, 4H), 3.32-3.36 (m, 4H), 3.16 (d, J=9.6 Hz, 1H), 3.06-3.13 (m, 4H), 2.72-2.87 (m, 3H). [M+H] calc'd for C26H33ClN6O3, 413; found, 413.
