Reaction Steps

1.25 M HCl in MeOH (6.0 mL) was added to tert-butyl 2-(4-((5-fluoropyridin-2-yl)methoxy)-2-oxopyridin-1(2H)-yl)-10-methyl-5,8,9,10-tetrahydropyrido[3′,2′:4,5]pyrrolo[2,3-d]azepine-7(6H)-carboxylate (0.12 g, 0.22 mmol) and the resulting solution was stirred under N2 at ambient temperature for 20 h. The resulting suspension was diluted with Et2O (30 mL), and the resulting solids were collected by filtration to provide the title compound (92 mg, 92%) as an off-white solid: mp 238-240° C.; 1H NMR (500 MHz, DMSO-d6) δ 9.43 (s, 2H), 8.62 (d, J=2.0 Hz, 1H), 8.02 (d, J=8.5 Hz, 1H), 7.84-7.80 (m, 2H), 7.67-7.64 (m, 1H), 7.30 (d, J=8.5 Hz, 1H), 6.19 (dd, J=7.5, 2.5 Hz, 1H), 5.98 (d, J=2.5 Hz, 1H), 5.23 (s, 2H), 3.73 (s, 3H), 3.40-3.37 (m, 2H), 3.34-3.30 (m, 4H), 3.18-3.14 (m, 2H); ESI MS m/z 420 [M+H]−; HPLC (Method A) 98.8% (AUC), tR=13.5 min.
