Versuchsvorschrift

To a solution of 2-methylpyridin-3-ol (11.8 g, 108 mmol) in DMF at 0° C. was added sodium hydride (60% dispersion in oil, 4.32 g, 108 mmol) in small portions and the reaction warmed to ambient temperature. To this mixture was added 5-bromo-3-nitropicolinonitrile (24.6 g, 108 mmol) and the reaction was stirred overnight at ambient temperature. The reaction was poured into water (1000 mL) and the aqueous layer extracted with EtOAc. The combined organic layers were washed with water and brine, dried over MgSO4 and concentrated in vacuo to yield 5-bromo-3-(2-methylpyridin-3-yloxy)picolinonitrile (15 g, 48%).
