To a solution of 2-amino-4-trifluoromethyl-5-iodo-benzoic acid methyl ester (1 g, 2.90 mmol) in dioxane (20 mL) were added 1-methyl-5-tributylstannanyl-1H-[1,2,3]triazole (2.02 g, 4.34 mmol) and Pd(dppf)2Cl2 (237 mg, 0.29 mmol) and the resulting mixture was stirred at 100° C. for 24 h. A portion of catalyst (0.1 equiv) was added and the mixture was stirred at 100° C. for an additional 7 h. The solvent was removed in vacuo to afford a dark oil. The residue was purified by flash chromatography (silica gel, EtOAc/hexanes (0:1000 to 40:60)) to provide the title compound as an off-white solid (357 mg, 41% yield). ES-MS: m/z 301.2 [M+H]+, rt 4.49 min.
