Potassium Carbonate → 2-Methyl-3-nitropyridine

Participants

Reaction Steps

A solution of 2-chloro-3-nitropyridine (20 g, 0.126 mol), methylboronic acid (8.3 g, 0.139 mol), tetrakis(triphenylphosphine)palladium (0) (14.58 g, 0.013 mol) and potassium carbonate (52.3 g, 0.378 mol) in anhydrous 1,4-dioxane (100 ml) was refluxed for 2 days. The reaction mixture was cooled to room temperature, filtered, and concentrated under reduced pressure. The resulting residue was purified with silica gel column chromatography (ethyl acetate/n-hexane=1/3, v/v) to give 14 g of the titled compound as brown oil.
