Versuchsvorschrift

A suspension of sodium methoxide (40.5 g, 0.750 mol) in 200 mL of methanol was slowly added to a solution of 2-chloro-3-nitro-pyridine (79.3 g, 0.500 mol) in 800 mL of methanol at 0° C. The reaction mixture was stirred for 4 hours and then poured into 1000 g of ice. The resulting precipitate was filtered, washed with water, and dried to give 2-methoxy-3-nitro-pyridine (70. g, 0.45 mmol, 90%) as a white solid.
