Reaction Steps

A mixture of 2-hydroxy-propionamide (1.0 g, 11.2 mmol) and N,N-dimethylformamide dimethyl acetal (1.06 g, 8.96 mmol) in dimethyl glycol (6 mL) was heated to 80° C. for two hours, then cooled to room temperature. T mixture was added to a solution of 5-hydrazino-4′-methyl-biphenyl-3-carboxylic acid methyl ester (1.2 g, 4.1 mmol) in HOAc (5 mL), and the mixture was heated to 80° C. for another two hours. The reaction mixture was cooled and volatiles were removed under reduced pressure. 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 to afford 5-[5-(1-hydroxy-ethyl)-[1,2,4]triazol-1-yl]-4′-methyl-biphenyl-3-carboxylic acid methyl ester as a white solid (410 mg, 29.76%).
