Versuchsvorschrift

To a solution of 3-(3-cyano-1H-Indol-4-yl)-3-phenyl-acrylic acid ethyl ester LVIII (620 mg, 1.96 mmol) in EtOH (30 ml) and EtOAc (15 ml) was added Degoussa-type catalyst (10% Pd/C wet, 70 mg). The reaction mixture was hydrogenated in a Parr apparatus at 55 psi of H2 for 19 hours. The reaction mixture was filtered through celite with EtOH, MeOH and EtOAc. The filtrate was concentrated to afford 3-(3-cyano-1H-Indol-4-yl)-3-phenyl-propionic acid ethyl ester LIX as a white solid in quantitative yield (648 mg).
