In this study, five N-phenyl-2-(2-oxobenzoxazoline-3-yl)acetamide derivatives bearing substituents with different lipophilic and electronic properties on N-phenyl ring, beside the nonsubstituted one, have been synthesized. Their structural characterization has been performed by spectral analyses such as IR, 1H NMR and CIMS. 1H NMR data clearly indicated that the title compounds in DMSO-d6 present as a mixture of two different rotamers
