A mixture of 4-Iodo-5-methyl-thiophene-2-carboxylic acid methyl ester (d, 1 mmol), 2,6-Difluoro-N-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-benzamide (c, 1 mmol), palladium catalyst (0.1 mmol), sodium bicarbonate (1 mmol) in a mixture of toluene (5 mL), water (1 mL), ethanol (1 mL) was heated at 100° C. for 24 h. The mixture was taken up with EtOAc (100 mL), washed with water (2×100 mL) and dried (Na2SO4). The oil obtained on concentration was purified by flash chromatography to give 4-[4-(2,6-Difluoro-benzoylamino)-phenyl]-5-methyl-thiophene-2-carboxylic acid methyl ester as a yellowish solid (50 mg).
