Reaction Steps

Diethyl azodicarboxylate (0.22 mL) was added via syringe to a solution of 1-{4-[5-(3-Hydroxy-phenyl)-1H-imidazol-2-yl]-pyridin-2-yl}-4-isopropyl-piperazine (304 mg) and triphenylphosphine (0.371 g) in a 1:1 mixture of isopropanol and dichloromethane (13 mL). The resultant solution was stirred at ambient temperature for 3 days and then washed with water. The organic phase was dried over magnesium sulfate and concentrated. The residue was purified by flash column chromatography (5% methanol in dichloromethane) to provide 1-{4-[5-(3-Isopropoxy-phenyl)-1H-imidazol-2-yl]-pyridin-2-yl}-4-isopropyl-piperazine (0.112 g).
