Procedure

A 20% solution of TiCl3 in H2O was added dropwise at 0° C. to a solution of the ethyl (RS)-(4-cyano-phenylamino)-[3-ethoxy-5-(3-hydroxy-2-methyl-3H-imidazol-4-yl)-phenyl]-acetate (355 mg, 0.844 mmol) obtained in Example 247.1 in MeOH (4.2 ml). The mixture was stirred for 3 h. at room temperature, subsequently poured into NaHCO3 solution/ice-water and extracted with CH2Cl2. The organic phase was dried, filtered and concentrated. The residue was purified by chromatography (SiO2, CH2Cl2→CH2Cl2/MeOH 95:5). There were obtained 50 mg (15%) of ethyl (RS)-(4-cyano-phenylamino)-[3-ethoxy-5-(2-methyl-3H-imidazol-4-yl)-phenyl]-acetate as a yellowish solid; MS: 405 ([M+H]+).
