Procedimiento

To a stirred solution of 3-benzylpyrrolyl methanol (1.8 mmol), 2-(5-fluoro-2-benzothienyl)-3-methylbutanoic acid (2.0 mmol) and 4-dimethylaminopyridine (2.0 mmol) in 20 ml of methylene chloride and 2 ml of DMF is added N,N'-dicyclohexylcarbodiimide (2.0 mml). The reaction mixture is stirred, under nitrogen, for about two hours and then filtered and extracted with water. The aqueous phase is extracted with ether. The combined organic phases are washed with saturated aqueous NaHCO3, water and saturated aqueous NaCl, dried over CaSO4 and solvent evaporated to yield 3-benzylpyrrolylmethyl 2-(5-fluoro-2-benzothienyl)-3-methylbutanoate.
