Complete assignment of the 1 H and 13 C NMR chemical shifts of new coumarin derivate was described in this paper. A new coumarin derivate was synthesized in good yield by reaction of 4chloro-3-nitrocoumarin and 6-nitrobenzothiazol-2amine in ethyl acetate in the presence of triethylamine. The complete spectral assignment was achieved using of 1D ( 1 H and 13 C NMR) and 2D ( 1 H1 H-COSY, NOESY, HSQC and HMBC) NMR experiments.
