실험 절차

To a solution of ethyl 7-(4-bromophenyl)-4,7-dioxoheptanoate (5B) (2.56 g, 7.5 mmol) and 5-(1H-imidazol-1-yl)pyridin-2-amine (1.20 g, 7.5 mmol) in 15 mL of ethanol was added Zn(OTf)2 (8.18 g, 22.5 mmol). The resultant mixture was heated at 120° C. for 4 h under microwave irradiation and then concentrated to dryness. The resultant residue was dissolved in EA, washed with water and brine, dried over MgSO4, concentrated and purified by silica gel column chromatography (PE:EA=6:1) to afford ethyl 3-(1-(5-(1H-imidazol-1-yl)pyridin-2-yl)-5-(4-bromophenyl)-1H-pyrrol-2-yl)propanoate as a brown oil (250 mg, 7.1%).
