Reaction Steps

To 4-(1,3-dioxolan-2-yl)-5-((2-(2-isopropyl-2H-1,2,4-triazol-3-yl)pyridin-3-yl)methoxy)-2-methoxypyridine (60 mg, 0.15 mmol, 1 eq.) in a RB flask was added HCl (6 N, 2.0 mL). The mixture was warmed to 40° C., O/N, cooled to rt, neutralized to pH 7-8 with NaHCO3(sat) solution, and extracted with EtOAc three times. The combined organic layers were washed with brine, dried over Na2SO4, and concentrated to give 5-((2-(2-isopropyl-2H-1,2,4-triazol-3-yl)pyridin-3-yl)methoxy)-2-methoxyisonicotinaldehyde (52.2 mg, 99%) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ 10.35 (s, 1H), 8.62 (dd, J=4.6, 1.2 Hz, 1H), 8.33 (s, 1H), 8.11 (dd, J=8.0, 1.2 Hz, 1H), 7.98 (s, 1H), 7.40 (dd, J=8.0, 4.7 Hz, 1H), 6.99 (s, 1H), 5.62 (s, 2H), 5.28 (sep, J=6.7 Hz, 1H), 3.82 (s, 3H), 1.46 (d, J=6.7 Hz, 6H). LRMS (M+H+) m/z 354.1.
