Reaction Steps
Into a 5 mL microwave vial were charged with methyl 3-(5-methylpyridin-2-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (250 mg, 0.71 mmol), 1-bromo-2,3-difluorobenzene (273 mg, 1.42 mmol), cesium carbonate (1.15 g, 3.54 mmol), tetra-n-butylammonium iodide (261 mg, 0.71 mmol), POPd (35 mg, 0.071 mmol), water (0.5 mL) and N,N-dimethylformamide (3 mL). The reaction mixture was subjected to microwave irradiation at 150° C. for 10 mins. After cooling, the reaction mixture was extracted with ethylacetate. The organic layer was washed with brine, dried, and concentrated under reduced pressure to give the residue which was purified by silica gel column to yield the title compound.
