실험 절차

Following the general method as outlined in Example 1, into a suspension of 5-bromo-1H-indole-2,3-dione in acetic acid was added 4-methoxybenzohydrazide. 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 53 mg of the title compound (57%) as a orange powder in 93% purity by HPLC (Rt: 4.11, gradient of 8 min, MaxPlot detection between 230 and 400 nm).
