Improved synthesis and characterization of 1,3,4,6-tetra-O-acetyl-2-(N-acetylacetamido)-2-deoxy-beta-D-glucopyranose.

A method from the 1960s to synthesize the N,N-diacetyl derivative of peracetylated beta-D-glucosamine was improved by assistance of molecular sieves. The melting point of the title compound was revised and the structure determined by means of X-ray diffraction.
