Reaction Steps
The (RS)-(4-cyano-phenylamino)-(3,5-diethoxy-2-fluoro-phenyl)-acetic acid (220 mg) described in example 2.15 was dissolved in THF (3.3 ml). n-Butanol (64 mg), triphenylphosphine (179 mg) and diethylazo dicarboxylate (122 mg) were added and the mixture was stirred for 3 h at room temperature. The mixture was concentrated and the product was purified by column chromatography to give 109 mg of (RS)-(4-cyano-phenylamino)-(3,5-diethoxy-2-fluoro-phenyl)-acetic acid butyl ester as an off-white solid. MS: 414 ([M+H]+)
