Aromatic nitrites are found to readily react with thiosemicarbazide and 4-amino-3-methyl-1,2,4-triazol-5-thione in a solution of polyphosphoric acid to give corresponding 2-amino-5-aryl-1,3,4-thiadiazoles.

An unprecedented method for the conversion of (Z)-3-chloro-3-arylacrylic acids to corresponding benzoic acids by stirring in POCl3 at 80 degrees C is reported. The benzoic acids formed in situ undergo condensation with 4-amino-5-aryl-3-mercapto-1,2,4-triazoles to yield s-triazolo[3,4-b][1,3,4]thiadiazoles in high yields. (C) 2014 Elsevier Ltd.

biochemically evaluated a class of 4‐amino‐1,2,4‐triazole‐3‐thiol small‐molecule inhibitors identified by high‐throughput screening. This class of compounds exhibits low‐micromolar (3.9–8.2 μM) inhibitory potency and remarkable specificity for A3G versus the related cytosinedeaminase, APOBEC3A. Chemical modification of inhibitors, A3G mutational screening, and thiol reactivity studies implicate C321, a residue
