Reaction Steps

A mixture of 5-((2-bromopyridin-3-yl)methoxy)-4-(1,3-dioxolan-2-yl)-2-methoxypyridine (1.1 g, 3.0 mmol, 1 eq.), Zn (CN)2 (704 mg, 6.0 mmol, 2.0 eq.), and Pd(PPh3)4 (346 mg, 0.3 mmol, 0.2 eq.) in DMF (10 mL) was heated at 125° C. for 2 h under N2. The mixture was cooled, filtered, concentrated, and purified on silica gel using a mixture of EtOAc and hexanes as eluent to give 3-((4-(1,3-dioxolan-2-yl)-6-methoxypyridin-3-yloxy)methyl)picolinonitrile (820 mg, 84%) as a white solid. 1H NMR (400 MHz, CDCl3) δ 8.71 (d, J=4.6 Hz, 1H), 8.12 (dd, J=8.0, 0.7 Hz, 1H), 7.88 (s, 1H), 7.60 (dd, J=8.0, 4.7 Hz, 1H), 6.95 (s, 1H), 6.16 (s, 1H), 5.37 (s, 2H), 4.18-4.00 (m, 4H), 3.92 (s, 3H). LRMS (M+H+) m/z 314.1.
