In support of a research program aimed at discovering orally bioavailable thrombininhibitors, 13C- labeled 3-aminopyrazinone acetamide thrombininhibitors have been prepared to aid in the structural elucidation of key metabolites during preclinical and clinical studies. A method for the 13C-labeling of pyrazinones utilizing 13C-glycine as a building block has been developed in a good overall yield
