Procedure

Copper(II) acetate (223 mg, 1.20 mmol), phenylboronic acid (164 mg, 1.32 mmol) and molecular sieve 4 Å were added to a solution of the ethyl (RS)-(4-cyano-phenylamino)-(3-ethyl-5-hydroxy-phenyl)-acetate (390 mg, 1.20 mmol) obtained in Example 200.1 in CH2Cl2 (12 ml). Pyridine (476 mg, 6.01 mmol) was added dropwise and the mixture was stirred for 60 h. under an atmosphere of air. The reaction mixture was concentrated and the residue was purified by chromatography (SiO2, CH2Cl2). There were obtained 391 mg (81%) of ethyl (RS)-(4-cyano-phenylamino)-(3-ethyl-5-phenoxy-phenyl)-acetate as beige crystals; MS: 401 ([M+H]+)
