Procedure
To a solution of 2-methyl-2-(3-piperidin-3-yl-phenoxy)-propionic acid benzyl ester (Preparation 2, Method C; 30 mg, 0.085 mmol) in 1 mL methylene chloride was added 4-isopropylphenoxyacetic acid (33 mg, 0.17 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (33 mg, 0.17 mmol) and allowed to stir 18 h at ambient temperature. The reaction was concentrated under reduced pressure and the resultant oil flash chromatographed with 30% ethyl acetate/hexanes to yield 35 mg (78%) of 2-(3-{1-[(4-Isopropyl-phenoxy)-acetyl]-piperidin-3-yl}-phenoxy)-2-methyl-propionic acid benzyl ester as a clear oil.
