Step 2 - Synthesis of 2, 6-dichloro- -methoxypyridine
To a solution of 2,6-dichloropyridin-3-ol (16.3 g, 0.1 mol) and K2C03 (41.4 g, 0.3 mol) in DMF (200 mL) were added Mel (21.3 g, 0.15 mol). The mixture was allowed to stir at 80 °C for 2 hours. The mixture was then diluted with water (200 mL) and extracted with EtOAc (200 mL x 3). The organic layer was washed with brine (200 mL x 3), dried over Na2S04, filtered and the solvent was concentrated in vacuo to provide 2,6-dichloro-3-methoxypyridine (17.0 g, yield: 96.0%).
1H- NMR (CDC13;400 MHz) δ 7.12-7.18 (m, 2H), 3.86 (s, 3H).
MS (M+H)+: 178 / 180 / 182.
