Synthesis and properties of 2,5-dihydro-3,6-dimethylpyrazine
Abstract
The structure of the self-condensation product of α-aminoacetone has been shown by n.m.r. spectroscopy to be 2,5-dihydro-3,6-dimethylpyrazine (I); the thermal instability of this dihydropyrazine is shown to be due to its dimerization.
