실험 절차

To a solution of 4-({[3-Butyl-5-(4-methoxy-phenyl)-2-phenyl-3H-imidazol-4-ylmethyl]-cyclohexylmethyl-amine (4.0 g, 9.31 mmol) and 3-acetoxyl-4-tert-butoxycarbonyl-benzyl bromide (3.37 g, 10.24 mmol, 1.1 eq.) in 50 ml anhydrous acetonitrile is added anhydrous potassium carbonate (2.82 g, 20.5 mmol, 2.2 eq.), the resulting mixture is stirred at room temperature for 1 h, then raised to 50° C., stirred overnight. The solid precipitate is filtered off, washed with ethyl acetate, the combined organics is concentrated to dryness, purified through silica gel flash chromatography to give 3.99 g of 4-({[3-Butyl-5-(4-methoxy-phenyl)-2-phenyl-3H-imidazol-4-ylmethyl]cyclohexylmethyl-amino}-methyl)-2-acetoxy-benzoic acid tert-butyl ester MS (+VE) m/z 680 (M+1).
