실험 절차

A mixture of 5-amino-1-(2-bromo-5-nitrophenyl)-3-(4-phenoxyphenyl)-1H-pyrazole-4-carboxamide (149 mg, 0.3 mmol, crude), CuI (5.7 mg, 0.03 mmol), N1,N2-dimethylethane-1,2-diamine (3 mg, 0.03 mmol), K3PO4 (64 mg, 0.3 mol) in 15 mL of DMF was stirred at 60° C. under N2 for 5 hr, until TLC analysis showed that most of starting material was consumed. The reaction was cooled to RT. The solvent was removed under reduced pressure. The residue was chromatographed on 5 g of silica gel using DCM/MeOH (200/1 to 20/1) to afford 62 mg (52%) of 7-nitro-2-(4-phenoxyphenyl)-4H-benzo[4,5]imidazo[1,2-b]pyrazole-3-carboxamide as a tan solid. MS (ESI) m/e [M+1]+ 414.
