Three-component green synthesis of 6-ethoxycarbonyl-5-methyl-7-(thien-2-yl)-4,7-dihydro[1,2,4]triazolo[1,5-a]pyrimidine, a promising antituberculosis drug

Аннотация

A new simple, technological, and environmentally friendly method for the catalyst-free synthesis in water of a promising antituberculosis drug, 6-ethoxycarbonyl-5-methyl-7-(thien-2-yl)-4,7-dihydro[1,2,4]triazolo[1,5-a]pyrimidine, was developed. The amount of the solvent in the reaction mixture has a decisive effect on the yield and purity of the target product.
