実験手順
Following the general method as outlined in Example 1, into a suspension of 5-iodo-1H-indole-2,3-dione in acetic acid was added 2-(4-nitrophenoxy)acetohydrazide. After stirring at 100° C., the reaction mixture was cooled to rt and a yellow solid precipitated out. Filtration on a fritté, washing with AcOH, water and drying under vacuo at 60° C. overnight gave 395 mg of the title compound (85%) as a yellow solid in 97.3% purity by HPLC (Rt: 5.76, gradient of 10 min, MaxPlot detection between 230 and 400 nm).
