Reaction Steps
An oven-dried resealable Schlenk tube was charged with 6-chloro-2-methoxy-3-nitropyridine (0.50 g, 2.6 mmol), 2-tributylstannanyloxazole (1.20 g, 3.4 mmol) and 1,4-dioxane (10 mL) and then subjected to several cycles of evacuation-backfilling with argon. Tetrakis(triphenylphosphine)palladium (0.18 g, 0.16 mmol) was then added and, after three new cycles of evacuation-backfilling with argon, the Schlenk tube was sealed and the mixture was stirred and heated in an oil bath to 110° C. After stirring overnight, water and ethyl acetate were added and the organic layer was washed with water, dried (MgSO4) and evaporated. The residue was purified by flash chromatography (2:1 hexanes/ethyl acetate) to give the title compound (0.38 g, 67%) as a yellow solid.
