Reaction Steps
Into a solution of 5-iodo-1H-indole-2,3dione (10.0 g, 36.6 mmol) in anhydrous DMF (180 ml) were added DBU (8.2 mL, 54.9 mmol) and methyl bromoacetate (5.1 mL, 54.9 mmol). After stirring at rt for 45 min, the reaction mixture was quenched with water (600 mL) and HCl (1N, 100 mL). Extraction with EtOAc (3×500 mL), drying over MgSO4 and evaporation under vacuo gave a residue. Recrystallization from AcOEt 150 mL) gave the title compound as an orange powder (6.45 g, 51%) in 99.1% purity by HPLC (MaxPlot detection between 230 and 400 nm).
