94.6% | With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In tetrahydrofuran; water; at 80℃; for 24h;Inert atmosphere; | A mixture of 4-methyl-naphthalene-1-boronic acid (5.00 g,26.8 mmol), <strong>[175205-81-9]2-bromo-4-(trifluoromethyl)pyridine</strong> (6.68 g,29.5 mmol), tetrakis(triphenylphosphine)palladium (0.31 g,0.26 mmol, 1 molpercent), potassium carbonate (75 ml, 2Maqueous solution), and tetrahydrofuran (150 mL) washeaded under a nitrogen atmosphere at 80 C for 24 h.This reaction is the Suzuki coupling reaction. After thereaction, the mixture was cooled to room temperatureand the flask was left in an ice bath for 2 h. The compoundwas extracted by liquid?liquid separation (water anddichloromethane). The compound was purified by a celitesilicagel filter (solvent: toluene) and column chromatographyon silica gel (eluent: hexane/ethyl acetate, 15:1).Yield: 94.6percent (7.306 g); 1H NMR (CDCl3, 500 MHz):H (ppm) 8.52 (d, 1H), 8.38 (d, 1H), 8.33 (d, 1H), 8.18(d, 1H), 8.06 (s, 1H), 7.54 (s, 1H), 7.52 (d, 1H), 7.15(d, 1H), 7.09 (s, 1H), 2.26 (s, 1H). |
