Dimethyl Sulfoxide → 1-(4'-{5-[(1-Benzyl-1H-[1,2,3]triazol-4-yl)-hydroxy-methyl]-1-methyl-1H-pyrazol-4-yl}-biphenyl-4-yl)-cyclopropanecarboxylic acid ethyl ester

Reaction Steps

1-{4′-[5-(1-Hydroxy-prop-2-ynyl)-1-methyl-1H-pyrazol-4-yl]-biphenyl-4-yl}-cyclopropanecarboxylic acid ethyl ester (0.17 g, 0.45 mmol) and benzyl azide (0.072 g, 0.54 mmol) were combined DMSO (5 mL). Copper(II) sulfate (0.001 g, 0.005 mmol) and sodium ascorbate (0.001 g, 0.05 mmol) were combined in H2O (2 mL) and the solution was added to the DMSO mixture. The reaction was stirred at room temperature for 18 hours then submitted to EtOAc/H2O workup. Purification on silica gel (0-70% EtOAc in hexanes) provided the title compound.
