Participants

Reaction Steps

To 5-((4-formyl-6-methoxypyridin-3-yloxy)methyl)nicotinate (96 mg, 0.32 mmol, 1 eq.) in a mixture of MeOH/THF (1/3, 8.0 mL) was added NaOH (3 N, 1.7 mL, 5.1 mmol, 16 eq.). The mixture was stirred at rt for 2 h, acidified to pH 3, extracted with EtOAc (3×20 mL). The combined organic layers were dried over Na2SO4 and concentrated to give 5-((4-formyl-6-methoxypyridin-3-yloxy)methyl)nicotinic acid (86 mg, 93%) as a white solid. 1H NMR (400 MHz, DMSO) δ 13.55 (s, 1H), 10.34 (s, 1H), 9.06 (d, J=1.9 Hz, 1H), 8.96 (d, J=2.0 Hz, 1H), 8.42 (t, J=2.0 Hz, 1H), 8.34 (s, 1H), 7.02 (s, 1H), 5.44 (s, 2H), 3.86 (s, 3H). LRMS (M+H+) m/z 289.1.
