Reaction Steps

To TEA hydrochloride salt (123 mg, 0.89 mmol, 4 equiv.) and 3-((4-formyl-6-methoxypyridin-3-yloxy)methyl)picolinonitrile (70 mg, 0.26 mmol, 1 equiv.) in chlorobenzene (5.0 mL) was added NaN3 (48 mg, 0.89 mmol, 4 equiv.) at rt. The mixture was heated to 110° C. for 2 h, cooled to rt, and added water (5.0 mL). The precipitate was filtered and washed with EtOAc and water and dried under high vacuo to give 5-((2-(2H-tetrazol-5-yl)pyridin-3-yl)methoxy)-2-methoxyisonicotinaldehyde as a white solid. 1H NMR (400 MHz; DMSO) δ=10.23 (s, 1H), 8.61 (d, 1H), 8.16 (s, 1H), 8.10 (d, 1H), 7.38 (dd, 1H), 6.96 (s, 1H) 5.73 (s, 2H), 3.83 (s, 3H). LRMS (M+H+) m/z 313.0.
