Reaction Steps
To a solution of 4-(1H-imidazol-2-yl)-2-methylaniline (Method #3) (1.0 g, 5.76 mmol) and ethyl 7-(4-methoxyphenyl)-4,7-dioxoheptanoate (25C) (2.03 g, 6.93 mmol) in EtOH (12 mL) was added Zn(OTf)2 (6.30 g, 17.34 mmol). The mixture was heated by microwave at 120° C. for 5 h. The solvent was removed under reduced pressure and the residue was dissolved in EA, washed with water and brine, dried over MgSO4, filtered, concentrated and purified by silica gel column chromatography (PE:EA=1:1) to afford ethyl 3-(1-(4-(1H-imidazol-2-yl)-2-methylphenyl)-5-(4-methoxyphenyl)-1H-pyrrol-2-yl)propanoate as a brown solid (755 mg, 30%).
