Triethylamine → [[(3-Nitrophenyl)amino]carbonyl]aminoacetic acid methyl ester

참여 물질

반응 단계

To a suspension of 3-nitrophenyl isocyanate (10 g, 61 mmol) and glycine methyl ester hydrochloride (8.4 g, 67 mmol, 1.1 equiv.) in dichloromethane (250 mL) was added triethylamine (10 mL, 72 mmol, 1.2 equiv.) at 0° C. The resulting solution was stirred at room temperature overnight. The resulting dark brown solution was concentrated and triturated in water to give a light yellow suspension. The suspension was filtered and the filter cake was washed with water and air-dried to give [[[(3-nitrophenyl)amino]carbonyl]aminoacetic acid methyl ester (15 g) in quantitative yield.
