Procedure

To a mixture containing 2-butyl-4-chloro-1-[[1-(2-cyanophenyl)-1H-indol-4-yl]methyl]-1H-imidazole-5-carboxylic acid (903 mg, 2.03 mmol, prepared as described in part C of Example 9), 5-indanol (307 mg, 2.29mmol), 2,6-dimethylaminopyridine (50.8 mg, 0.416 mmol) and triethylamine (0.377 mL, 2.70 mmol) in 9 mL of dichloromethane cooled in an ice bath was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (519 mg, 2.70 mmol). The stoppered reaction mixture was allowed to warm to ambient temperature overnight, then diluted with methylene chloride and rinsed with water and saturated aqueous sodium chloride solution. The organic extract was dried over anhydrous magnesium sulfate and concentrated in vacuo to give 1.83 g of crude product. Flash chromatography on 75 g of silica gel eluted with 8:2, hexanes:ethyl acetate gave 1.03 g of the title A compound.
