実験手順
A mixture of 5-amino-3-(4-phenoxyphenyl)-1H-pyrazole-4-carboxamide (29.4 mg, 0.1 mmol) and 2-bromo-1-(3-nitrophenyl)ethanone (24.4 mg, 0.1 mmol) in EtOH (2 mL) was stirred at 80° C. for 16 hr. The mixture was filtered to afford 5 mg of crude 2-(3-nitrophenyl)-6-(4-phenoxyphenyl)-1H-imidazo[1,2-b]pyrazole-7-carboxamide as a yellow solid. MS (ESI) m/e [M+1]+ 440.0.
