Procedure

Pd-C (10%, 236 mg, 0.22 mmol) was added a solution of the ethyl (RS)-(4-cyano-phenylamino)-(3-methoxy-5-vinyl-phenyl)-acetate (1.495 g, 4.44 mmol) obtained in Example 198.3 in EtOH (40 ml) and THF (4 ml) and the mixture was hydrogenated for 1 h. at room temperature. The reaction mixture was filtered, the filtrate was concentrated and the residue was purified by filtration over SiO2 (eluent: AcOEt/hexane 1:1). There were obtained 1.5 g (99%) of ethyl (RS)-(4-cyano-phenylamino)-(3-ethyl-5-methoxy-phenyl)-acetate as a beige solid; MS: 338 ([M]+).
