Water → Ethyl ((2-(aminocarbonyl)-4-methoxyphenyl)amino)(oxo)acetate

Participants

Reaction Steps

To a solution of 2-amino-5-methoxybenzamide (1.50 g, 9.03 mmol) and triethylamine (1.00 g, 9.93 mmol) in THF (40 mL) was added dropwise ethyl chloroglyoxylate (1.36 g, 9.93 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 filtered cake was washed with water and ethanol to give ethyl ((2-(aminocarbonyl)-4-methoxyphenyl)amino)(oxo)acetate as a pale-yellow powder (2.42 g, 100%).
