Reaction Steps

Add sodium hydride (1.3 g, 42 mmol) to a mixture of 2-phenyl-1H-imidazole (5.0 g, 35 mmol), 8-bromooctanoic acid methyl ester (8.22 g, 35 mmol), potassium carbonate (5.75 g, 42 mmol), and tetra-n-butylammonium iodide (0.77 g, 2 mmol) in DMF (250 mL) at 0° C. under nitrogen. Heat the mixture to 75° C. and stir for 21 hours. Remove the solvent under reduced pressure, dissolve the residue in chloroform (200 mL), wash with water (100 mL) and brine (100 mL), and dry over sodium sulfate. Remove the solvent under reduced pressure and purify the residue by flash column chromatography on silica gel, eluting with methanol/methylene chloride (1:9), to afford 8-(2-phenylimidazol-1-yl)octanoic acid methyl ester (4.90 g, 47%).
