## Abstract

The synthesis and selected aspects of the UV, IR, and $^1H$ NMR spectra of the title compound are described. The crystals of the title compound are triclinic with a = 12.999(9), b = 8.911(4), c = 9.199(5) \AA ; \alpha = 105.56(3), \beta = 113.50(4), \gamma = $92.53(3)^o$; Z = 2; space group P1. Its X-ray crystal structure analysis provides information regarding the conformational features of the amide linkage when no intermolecular hydrogen bonding involving this group is present. The X-ray study shows that the C ' - N bond is longer [1.363(4) \AA ] than that found normally in peptide molecules. The compound shows a peculiar disorder involving one of the two amide groups present in the molecule. The conformation of the N-methyl acetanilide moiety and its relation to the $^1H$ NMR spectrum of the compound are discussed.
