Reaction Steps
TFAA (2.5 mL, 17.7 mmol) was added at 0° C. to a stirred mixture of 1-(3′-methylsulfonyl)biphenyl-4-yl)-2-(2-(trifluoromethyl)phenyl-1H-imidazole-4-carboxamide (3.97 g, 8.177 mmol), Et3N (5 mL, 35.87 mmol), and dry DCM (100mL), the resulting mixture was stirred at 0° C. for 2 h. The solvent was removed in vacuo, the residue was purified by flash chromatography (SiO2, 80% EtOAc/hexanes) to give 1-(3′-methylsulfonyl)biphenyl-4-yl)-2-(2-(trifluoromethyl)phenyl-1H-imidazole-4-carbonitrile as a pale-yellow to white solid (3.13 g, 82%). MS (ESI) 468 [M+H]+.
