To 2-bromo-6-methyl-3-(2H-1,2,3-triazol-2-yl)pyridine (1.5 g, 7.6 mmol) in DMF (19 mL) was added K2CO3 (1.2 g, 8.4 mmol) and 2H-1,2,3-triazole (440 μL, 7.6 mmol). The mixture was heated to 100° C. for 16 h, cooled to rt and extracted with EtOAc (2×). The combined organics were dried (Na2SO4) and concentrated. Purification via silica gel chromatography (5-60% EtOAc in hexanes) gave the title compound (490 mg, 35%) and 5-methyl-3-(1H-1,2,3-triazol-1-yl)picolinonitrile (387 mg, 27%).
