摘要

The synthesis of analog of Triazavirin (Riamilovir) enriched with isotopic 13C and 15N labels, viz. monohydrate of l-arginine salt of 5-methyl-6-nitro-7-oxo-4,7-dihydro[1,2,4]triazolo[1,5-a]pyrimidine was developed. To incorporate 13C and 15N stable isotopes into its structure, [5-13C]-3-amino-1,2,4-triazole (13C, 99
