Reaction Steps

To a solution of 3-bromo-4-nitro-1H-indazole (1.5 g, 6.20 mmol) in DMF (0.5M, 12 mL) was added potassium carbonate (1.71 g, 12.4 mmol) at ambient temperature. After 15 minutes, 2-(chloromethyl)-6-ethoxypyridine hydrochloride (1.29 g, 6.20 mmol) was added. The mixture was allowed to stir at ambient temperature for 18 hours. The mixture was concentrated and diluted with ice-water (300 mL). Precipitated solids were collected by filtration, washed with water and dried under high vacuum overnight to provide 3-bromo-1-((6-ethoxypyridin-2-yl)methyl)-4-nitro-1H-indazole (1.21 g, 52% yield).
