The title compound, C6H14N2O, was synthesized by the reaction between 2-amino-2,3-dimethylbutanonitrile and oil of vitriol (sulfuric acid). A racemic mixture of L- and R-2-amino-2,3-dimethylbutanamide was characterized crystallographically. In the crystal structure, intermolecular N-HO hydrogen bonds link the two enantiomers into a three-dimensional network.
2-Amino-2,3-dimethylbutanamide, a common intermediate in the synthesis of imidazolinone compounds, is an excellent weedicide, usually used as racemic mixture of the levo and dextral enantiomers, see: Goatz et al. (1990); Harir et al. (2007).
