Versuchsvorschrift

tert-Butyl 5-methyl-7-(2-oxo-4-(4-(trifluoromethyl)phenyl)pyridin-1(2H)-yl)-3,4-dihydro-1H-pyrido[4,3-b]indole-2(5H)-carboxylate (95 mg, 0.18 mmol) was dissolved in MeOH (2 mL) and 2 N HCl in Et2O (10 mL) was added. The reaction was allowed to proceed for 3 h. The resulting precipitate was collected by filtration and washed with Et2O to provide the title compound (45 mg, 50%) as a pale yellow solid: mp 318-323° C.; 1H NMR (500 MHz, CD3OD) δ 7.95 (d, J=8.2 Hz, 2H), 7.84 (d, J=8.2 Hz, 2H), 7.81 (d, J=7.1 Hz, 1H), 7.63 (d, J=8.3 Hz, 1H), 7.57 (s, 1H), 7.14 (dd, J=8.3, 1.3 Hz, 1H), 6.96 (d, J=1.6 Hz, 1H), 6.87 (dd, J=7.1, 1.7 Hz, 1H), 4.50 (s, 2H), 3.76 (s, 3H), 3.68 (t, J=6.1 Hz, 2H), 3.22 (t, J=6.1 Hz, 2H); ESI MS m/z 424 [M+H]+; HPLC (Method B) 97.6% (AUC), tR=13.9 min.
