To a solution of 2-methyl-2-(3-piperidin-3-yl-phenoxy)-propionic acid benzyl ester (Preparation 2, Method C; 0.54 g, 1.52 mmol) in 5 mL methylene chloride was added 4-isopropylphenyl acetic acid (0.33 g, 1.83 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.58 g, 3.04 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 0.696 g (89%) of 2-(3-{1-[(4-Isopropyl-phenyl)-acetyl]-piperidin-3-yl}-phenoxy)-2-methyl-propionic acid benzyl ester as a clear oil.
