YieldReaction ConditionsOperation in experiment
60% Ina 35 mL eggplant flask, compound 12 (758.3 mg, 2.516 mmol) was dissolved in1,4-dioxane (20 mL), then bis (pinacolato) diboron (842.3 mg, 3.317 mmol),tricyclohexylphosphine (93.7 mg, 0.334 mmol), tris (dibenzylideneacetone) di palladium(0) (115.0 mg, 0.126 mmol), further potassium acetate (511.1 mg, 5.207 mmol) wereadded, replaced with argon and the mixture was stirred for 2 hours from 100 to 110C. The reaction solution wascooled to room temperature, filtered through Celite and the filtrate wasconcentrated under reduced pressure. The obtained residue was dissolved in in1,4-dioxane (6 mL) and water (3 mL), then 2- chloro-4-iodo-6-trifluoromethylpyridine 4 (519.3 mg, 1.689 mmol), tetrakis (triphenyl phosphine) palladium (0)(102.3 mg, 0.089 mmol) and sodium carbonate (565.8 mg, 5.338 mmol) were addedand heated under reflux for 30 minutes. The reaction mixture was cooled to roomtemperature, then water (20 mL) was added, and extracted twice with ethylacetate and dried with anhydrous Na2SO4, then the solventwas evaporated. The resulting residue was purified by silica gel columnchromatography (BW-200, 18 g, eluent; 3% ? 5% ? 15% benzene / n- hexane) togive the compound 3k (404.9 mg, 1.007 mmol, 60% from 5 ).
