Reaction Steps

A mixture of 2-chloro-3-nitropyridine (1.00 g, 6.30 mmol), potassium carbonate (2.62 g, 18.90 mmol), tetrakis(triphenylphosphine)palladium (0.73 g, 0.63 mmol) and trimethyl boroxine (0.88 mL, 6.30 mmol) in 1,4-dioxane (2 mL) and water (8 mL) was heated to 110° C. (oil bath temperature) for 6 h and then stirred for 16 h at rt. The mixture was then filtered through a celite pad, washing through with THF. The filtrate was adsorbed onto silica gel in vacuo and purified via flash column chromatography eluting with ethyl acetate/hexanes (3:7) to give the title compound as a yellow solid. δH (CDCl3): 2.86 (3H, s), 7.34 (1H, dd), 8.26 (1H, dd), 8.71 (1H, dd).
