Versuchsvorschrift

A flask was charged with 2-methylpyridin-3-ol (3.0 g, 27.5 mmol) and DMF (100 mL). Sodium hydride (0.760 g, 30.2 mmol) was added and stirred for 5 minutes. 5-Bromo-3-nitropicolinonitrile (6.26 g, 27.5 mmol) was added and stirred for 10 minutes. The reaction was poured into a flask containing 300 mL saturated NH4Cl and 300 mL water with vigorous stirring. The solids were filtered and dried under high vacuum to afford 5-bromo-3-(2-methylpyridin-3-yloxy)picolinonitrile (7.78 g, 97.6% yield) as light tan solid.
