Potassium acetate (0.6 g, 6.0 mmol) was weighed directly into the flask. The flask was then evacuated and back filled with N2. Anhydrous N,N- dimethylformamide (DMF) (13.0 mL) was added and the reaction was heated at 80 0C in an oil bath overnight. The reaction mixture was evaporated to dryness. The residue was dissolved in ethyl acetate (10 mL) and washed with water (1OmL). The organics were dried over sodium sulfate and evaporated to dryness. The resulting material was purified by silica gel chromatography (eluting with 0-100% ethyl acetate in hexanes) to yield the product (0.47 g, 78%). ESI-MS m/z calc. 269.53, found 270.3 (MW+1)+. Retention time 2.07 minutes.

78% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In 1,4-dioxane; water; at 90℃; for 16.0h;Inert atmosphere; [0153] To a solution of <strong>[848366-28-9]5-bromo-3-chloro-2-methoxypyridine</strong> (5.0 g, 22.5 mmol), and 3,5-dimethylisoxazole-4-boronic acid pinacol ester (6.0 g, 27.0 mmol) in 1,4-dioxane (188 mL) and water (19 mL) was added potassium carbonate (6.2 g, 44.9 mmol). The mixture was purged with nitrogen for 10 min, and tetrakis(triphenylphosphine)palladium(0) was added (1.3 g, 1.12 mmoi). The mixture was heated to 90 C for 16 h, then diluted with ethyl acetate (100 mL) and washed with brine (100 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by chromatography (silica gel, 0- 30% ethyl acetate/hexanes) to afford 4 as a white solid (4.2 g, 78%): JH NMR (300 MHz, DMSO-d6) delta 8.18 (d, J = 2.1 Hz, 1H), 8.01 (d, J - 2.1 Hz, 1H), 3.99 (s, 3H), 2.40 (s, 3H), 2.22 (s, 3H); ESI m/z 239 [M + H]+.

With potassium phosphate; palladium diacetate; tricyclohexylphosphine; In water; toluene; at 100℃;Inert atmosphere; To a mixture of cyclopropylboronic acid (1.26 g) , 5- bromo-3-chloro-2-methoxypyridine (2.50 g) , toluene (30 ml) and water (3 ml) were added palladium(II) acetate (126 mg) , tricyclohexylphosphine (315 mg) and tripotassium phosphate (7.16 g) , and the mixture was stirred under a nitrogen (1052) atmosphere at 100C overnight. Water was added to the mixture and the mixture was extracted with^ ethyl acejtate . The._organic . layer was separated, washed with water and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (1.20 g) . (1053) MS: [M+H]+ 184.3.
