실험 절차

tert-Butyl 7-(4-(2,4-dichlorophenyl)-2-oxopyridin-1(2H)-yl)-5-methyl-3,4-dihydro-1H-pyrido[4,3-b]indole-2(5H)-carboxylate (56 mg, 0.11 mmol) was dissolved in MeOH (1 mL) and 2 N HCl in Et2O (5 mL) was added. The reaction was allowed to proceed for 3 h. The mixture was concentrated and purified by preparative HPLC. Conversion to the HCl salt (2 N HCl in Et2O) provided the title compound (22 mg, 42%) as a yellow solid: mp 321-324° C.; 1H NMR (500 MHz, CD3OD) δ 7.80 (d, J=7.0 Hz, 1H), 7.70 (s, 1H), 7.68 (d, J=7.9 Hz, 1H), 7.62 (s, 1H), 7.54 (s, 2H), 7.13 (d, J=7.0 Hz, 1H), 6.73 (s, 1H), 6.61 (d, J=7.2 Hz, 1H), 4.54 (s, 2H), 3.80 (s, 3H), 3.72 (t, J=6.0 Hz, 2H), 3.26 (t, J=5.9 Hz, 2H); ESI MS m/z 424 [M+H]+; HPLC (Method B)>99% (AUC), tR=14.1 min.
