A general, post-synthetic labeling method for the preparation of fully deuterated pyrazoles and quinoxalines by base-induced isotope exchange in superheated deuterium oxide is described. Examples include the synthesis of 2-methylquinoxaline-d8, 2,3-dimethylquinoxaline-d10, 3,5-dimethylpyrazole-d8, and 3,5-diphenylpyrazole-d12. © 1997 Published by Elsevier Science Ltd.
