Reaction Steps

Triphenylphosphine (2.10 g, 1.89 mmol) and potassium carbonate (7.80 g, 56.7 mmol) were added to a slurry of 4-chloro-3-nitropyridine (3.00 g, 18.9 mmol, CAS RN 13091-23-1) and 2-tolylboronic acid (2.83 g, 20.8 mmol, CAS RN 16419-60-6) in dioxane stirring under an argon atmosphere. The reaction mixture was heated to 120° C. for 16 hours and then cooled to room temperature. The solids were removed by filtration through celite and all volatiles were removed in vacuo resulting in a dark colored heavy oil. The product was isolated as a heavy oil by flash chromatography on silica gel (25-33% EtOAc in n-hexane) (1.75 g, 43%).
