The M y proton-coupled 15N NMR spectra of pyrimidine with natural isotope abundance and of bis-labelled [1,3-"N2]p~dine, obtained using single pulse experiments, are described. The "N and 'H spectra are analysed for "J, 'J and 4J(NH) as well as N,N and H,H coupling constants.
4-15N-2,3,5-Trimethylpyrazine (A) was synthesized by dechlorination of 4-15N-6-chloro-2,3,5-trimethylpyrazine (I), the key intermediate, derived from 15N-D~alanine (a). 1-15N-2, 3,5-Trimethylpyrazine (2) was prepared by decarboxylation of 1-15N-2,3,5-trimethyl-pyrazine-6- carboxylic acid (10) obtai
