Versuchsvorschrift

(S)-3-((R,Z)-6-(benzyloxy)-2-(4-fluoro-3-methylphenoxy)hex-4-enoyl)-4-isopropyloxazolidin-2-one (250 mg, 0.54 mmol) was dissolved into 5 mL EtOH and to it added 10% Pd/C (250 mg). The solution was saturated with H2 (stream of H2 bubbled through solution) and then stirred for 3 h at room temperature under an atmosphere of hydrogen balloon. The mixture was filtered through a bed of Celite and rinsed with ethyl acetate. The solvent was removed under reduced pressure and the crude product used directly in the next step without further purification.
