Hi my apologies as you have not been provided 13C NMR & Mass spectra, but luckily i have 13C NMR of this compound only.
The compound is 3-Methyl-3-ethylglutarimide (also called as Bemegride )
IR:
3207 cm-1, medium, imide N-H stretch
2980 & 2904 cm-1, medium, sp3 alkyl C-H stretch
1730 cm-1, medium, imide C=O symmetric & asymmetric stretch
1678 cm-1, strong, imide N-H bending
1387 cm-1, strong, sp3 alkyl C-H bending
1278 cm-1, imide keto-enol tautomer C-O stretch
HNMR & CNMR:
Hope this helped you!
