Procedure

1.25 M HCl in MeOH (3.2 mL) was added to tert-butyl 10-methyl-2-(2-oxo-4-(6-(trifluoromethyl)pyridin-3-yl)pyridin-1(2H)-yl)-5,8,9,10-tetrahydropyrido[3′,2′:4,5]pyrrolo[2,3-d]azepine-7(6H)-carboxylate (55 mg, 0.10 mmol), and the resulting solution was stirred under N2 at ambient temperature for 18 h. The solution was diluted with MeOH (2.2 mL) and Et2O (25 mL), and the resulting solids were collected by filtration to provide the title compound (37 mg, 76%) as a yellow powder: mp 320-325° C. dec; 1H NMR (500 MHz, DMSO-d6) δ 9.28 (s, 2H), 9.21 (d, J=2.0 Hz, 1H), 8.50 (dd, J=8.5, 2.0 Hz, 1H), 8.10-8.04 (m, 3H), 7.41 (d, J=8.0 Hz, 2H), 7.03 (d, J=1.5 Hz, 1H), 6.85 (dd, J=7.5, 3.5 Hz, 1H), 5.98 (d, J=2.5 Hz, 1H), 3.76 (s, 3H), 3.41-3.40 (m, 2H), 3.33-3.31 (m, 2H, overlaps with solvent), 3.17 (t, J=5.5 Hz, 2H); ESI MS m/z 440 [M+H]+; HPLC (Method A) 99.0% (AUC), tR=13.6 min.
