Versuchsvorschrift

tert-Butyl 7-(4-(4-chlorophenyl)-2-oxopyridin-1(2H)-yl)-5-methyl-3,4-dihydro-1H-pyrido[4,3-b]indole-2(5H)-carboxylate (59 mg, 0.12 mmol) was dissolved in MeOH (0.5 mL) and 2 N HCl in Et2O (3 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, 40%) as a pale yellow solid: 1H NMR (500 MHz, CD3OD) δ 7.80-7.78 (m, 3H), 7.66 (d, J=8.5 Hz, 1H), 7.58-7.57 (m, 3H), 7.16 (dd, J=8.3, 1.7 Hz, 1H), 6.94 (d, J=1.8 Hz, 1H), 6.87 (dd, J=7.1, 1.9 Hz, 1H), 6.17 (d, J=2.7 Hz, 1H), 4.53 (s, 2H), 3.79 (s, 3H), 3.72 (t, J=5.9 Hz, 2H), 3.25 (t, J=5.9 Hz, 2H); ESI MS m/z 390 [M+H]+; HPLC (Method B) 98.2% (AUC), tR=16.3 min.
