Participants

Reaction Steps

To a solution of 2-amino-5-iodobenzamide (15.8 g, 60.3 mmol) and triethylamine (7.32 g, 72.4 mmol) in THF (300 mL) was added dropwise ethyl chloroglyoxylate (9.05 g, 66.3 mmol) under ice-cooling, and the mixture was stirred at room temperature for 2 hr. Water was added to the reaction mixture, and the precipitated insoluble material was collected by filtration. The solid was washed with water to give ethyl ((2-(aminocarbonyl)-4-iodophenyl)amino)(oxo)acetate as a white powder (20.9 g, 96%).
