To a mixture of 4-(2-((1H-tetrazol-5-yl)methyl)-5-(4-bromophenyl)-1H-pyrrol-1-yl)phenol (1.0 g, 2.52 mmol) and 2-methyl-1H-imidazole (2.07 g, 25.2 mmol) in DMSO (10.0 mL) was added 8-HQ (54 mg, 0.38 mmol), Cu2O (0.29 g, 2.52 mmol), Cs2CO3 (0.986 g, 3.03 mmol) and PEG-2000 (0.29 g). The resultant mixture was heated at 150° C. for 3 h under microwave irradiation. The mixture was treated with EA (60 mL), the resultant precipitate was filtered and purified by Biotage-flash (Solid phase: C18; Mobile phase: A: CH3CN, B: H2O (0.05% CF3COOH); gradient: 12%→24% B in A; flow rate: 40 mL/min) to afford an off white solid (143 mg, yield 14%)
