The relative stereochemistry of the title compound, C~16~H~22~N~4~O~2~, a key intermediate in the synthesis of 3-deoxy imino sugars, was firmly established by X-ray crystallographic analysis. The absolute configuration was inferred from the starting material, D-galactose. There are no unusual crysta

All interatomic distances of the title compound, C 17 H 17 N 3 O 2 , are normal. The phenyl ring of the benzylaminomethyl substituent is disordered over two positions. The heteroatom ring of the quinoxolinone system shows a half-chair conformation. The molecules are held together by intermolecular N
