Procedure

2-(4-Trifluoromethoxyphenoxy-3-(4-benzyloxyphenyl)-2-methyl-propionic acid ethyl ester (2.1 mmol) was dissolved in ethyl acetate (30 mL) and treated with 5% palladium on carbon (300 mg), and stirred under an atmosphere of hydrogen for 20 h. The suspension was filtered through celite and concentrated in vacuo to an oil.

Workup

  1. filtrationThe suspension was filtered through celite and
  2. concentrationconcentrated in vacuo to an oil
