実験手順

To a solution of 5-hydrazino-4′-methyl-biphenyl-3-carboxylic acid methyl ester (300 mg, 1.17 mmol) in HOAc (5 mL) was added N-dimethylaminomethylene-isobutyramide (233 mg. 1.4 mmol) in one portion. The mixture was heated to 90° C. for two hours. After removing the excess HOAc, the residue was dissolved in EtOAc and washed with saturated aqueous NaHCO3. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by flash chromatography (ISCO™) to afford 5-(5-isopropyl-[1,2,4]triazol-1-yl)-4′-methyl-biphenyl-3-carboxylic acid methyl ester a yellow solid (293 mg, 74.6%).
