実験手順: To a sealed tube were added 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (2.2 g, 10 mmol), ethyl 2-(4-iodophenyl)acetate 26-1 (2.9 g, 10 mmol), Pd(PPh3)4 (0.231 g, 0.2 mmol), toluene (30 mL), ethanol (10 mL) and 2M Na2CO3 (10 mL). The reaction mixture was flushed with nitrogen and stirred at 90° C. for 10 hours. After cooled down to room temperature, the reaction mixture was diluted into 200 mL ethyl acetate and washed with saturated sodium bicarbonate solution and then brine. The organic phase was dried over Na2SO4 and then taken to dryness by rotary evaporation. The crude product was purified by silica gel flash chromatography, eluted with 50% ethyl acetate in hexane to give ethyl 2-(4-(2-methylpyridin-4-yl)phenyl)acetate 26-2 as an oil. MS m/z 256.1 (M+1). The reaction mixture was flushed with nitrogen After cooled down to room temperature the reaction mixture was diluted into 200 mL ethyl acetate washed with saturated sodium bicarbonate solution The organic phase was dried over Na2SO4 taken to dryness by rotary evaporation The crude product was purified by silica gel flash chromatography eluted with 50% ethyl acetate in hexane
