New ethyl 4-(5-cyano 4-oxo-6-arylamino-3,4-dihydro-2H-[1,3]thiazin-2-yl)-1-phenyl-1H-pyrazole-3- carboxylates were prepared from 2-cyano-3-mercapto-3-phenylamino-acrylamide and ethyl 4-formyl-1-phenyl-1H- pyrazole-3-carboxylate. Their antioxidant properties were evaluated by methods of scavenging effect on 2,2- diphenyl-1-picrylhydrazyl (DPPH) radicals. The results show that the ethyl 4-[5-cyano-6-(naphthalen-1-ylamino)-4- oxo-3,4-dihydro-2H-[1,3]thiazin-2-yl]-1-phenyl-1H-pyrazole-3-carboxylate have the best activity. [ABSTRACT FROM AUTHOR]
