YieldReaction ConditionsOperation in experiment
67% tetrakis(triphenylphosphine) palladium(0); In 1,4-dioxane; at 110℃;Schlenk tube; 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 0C. 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. δ 1H-NMR (CDCI3): 4.24 (s, 3H), 7.38 (s, 1 H), 7.84 (d, 1 H), 7.87 (s, 1H), 8.40 (d, 1H).ESI/MS m/e: 222 ([M+H]+, C9H7N3O4)

YieldReaction ConditionsOperation in experiment
With triethylamine;palladium diacetate; In water; ethyl acetate; N,N-dimethyl-formamide; Synthesis of ethyl (E)-3-(6-methoxy-5-nitropyridin-2-yl)acrylate Palladium acetate (386 mg), 2-(di-tert-butylphosphino)biphenyl (1.03 g), triethylamine (9.59 mL) and ethyl acrylate (18.6 mL) were added to a solution of 6-chloro-2-methoxy-3-nitropyridine (6.49 g) in DMF (100 mL). The reaction solution was stirred in a nitrogen atmosphere at 120°C for two hours and then left to cool to room temperature. The reaction solution was concentrated under reduced pressure. Water and ethyl acetate were added to the resulting residue, and the organic layer was separated. The resulting organic layer was washed with water and brine, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent: heptane-ethyl acetate system) and crystallized from heptane to obtain 2.1 g of the title compound. The property values of the compound are as follows. 1H-NMR (CDCl3) delta (ppm): 1.37 (t, J=7.6Hz, 3H), 4.15 (s, 3H), 4.30 (q, J=7.6Hz, 2H), 7.00 (d, J=16.0Hz, 1H), 7.09 (d, J=8.4Hz, 1H), 7.56 (d, J=16.0Hz, 1H), 8.28 (d, J=8.4Hz, 1H).
