Reaction Steps
To a stirred solution of (RS)-N-(4-cyano-benzyl)-2-ethoxy-2-(3-hydroxy-4-methoxy-phenyl)-acetamide (0.158 g) at rt in DMF (1.5 ml) were added K2CO3 (0.067 g) and ethyl bromoacetate (0.081 g). The reaction mixture was then stirred at rt under an argon atmosphere for 24 h. The mixture was diluted with EtOAc (10 ml), washed with water (10 ml+10 ml) and brine (10 ml), dried (MgSO4), filtered and concentrated (rotavapor). The product was purified by chromatography (Silicagel (20 g) using a gradient profile: cyclohexane to cyclohexane/EtOAc 45:55) to give (RS)-{5-[(4-cyano-benzylcarbamoyl)-ethoxy-methyl]-2-methoxy-phenoxy}-acetic acid ethyl ester (0.160 g) as a colorless gum.
