Chemical shifts (δ, ppm) and coupling constants (J, Hz, in parenthesis) obtained of 1D ¹H-NMR spectrum.

¹⁵N NMR spectrum of the compound 2 shows four signals corresponding to four nitrogen atoms and assigning each signal to its corresponding nitrogen atom is carried out based mainly on the spectral data ¹H-¹⁵N HMBC (Figure 3).
