Water → Methyl 2'-cyano-5-(5-methylpyridin-2-yl)-5'-(trifluoromethyl)biphenyl-3-carboxylate

Into a 5 mL microwave vial were charged methyl 3-(5-methylpyridin-2-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (300 mg, 0.85 mmol), 2-bromo-4-(trifluoromethyl)benzonitrile (425 mg, 1.70 mmol), cesium carbonate (1.38 g, 4.25 mmol), tetra-n-butylammonium iodide (314 mg, 0.85 mmol), POPd (43 mg, 0.085 mmol), water (0.6 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 afford the residue which was purified by silica gel column to yield the title compound.
