Synthesis and detailed spectral analysis of a new 4-substituted coumarin-amino acid derivate are presented in this paper. A new glycine derivate of (3-nitro-2-oxo-2H-chromen-4-yl)amino]acetate was prepared by condensation of 4-chloro-3-nitrocoumarin and ethyl glycinate hydrochloride. The complete assignment of 1H and 13C NMR chemical shifts of the synthesized compound was carried out by the aid of a combination of 1D (1H and 13C NMR) and 2D (1H-1H-COSY, NOESY, HSQC and HMBC) NMR experiments.
