Reaction Steps

A suspension of the ethyl (RS)-(4-cyano-phenylamino)-(4-hydroxy-3-methylsulphanyl-phenyl)-acetate (198 mg, 0.58 mmol) described in Example 168.1, Cs2CO3 (227 mg, 0.64 mmol) and isopropyl iodide (58 μl, 0.58 mmol) in acetone (3 ml) was heated under reflux for 4 h. Water was added and the mixture was extracted with CH2Cl2. Die organic phase was dried, filtered and concentrated. The residue was purified by chromatography (SiO2, hexane/EtOAc 2:1). Ethyl (RS)-(4-cyano-phenylamino)-(4-isopropoxy-3-methylsulphanyl-phenyl)-acetate (140 mg, 63%) was obtained as a colorless oil; MS: 443 ([M+OAc]−).
