, p. 1359 - 1372 (2007/10/03)

The possibility of the arylation of 5-amino-3-methylthio-1H-1,2,4-triazole (1) with different chlorobenzenes activated by a nitro group was studied.The ratio of products obtained was determined by hplc using isolated products as standards.It was stated that from among the monoarylated products 8, 9 and 10 obtained the main product is 8.However, from the reaction mixtures diarylated derivatives 11 and 12 and different by products such as 15, 16, 22, 24, 25, 27, 28, 32, 36, and 38 were also isolated.
