Abstract :A series of 3-alkyl-4-insert ignore into journalissuearticles values(arylidenamino);-4,5-dihydro-1H-1,2,4-triazol-5-ones, {\bfseries 6-10,} was obtained from the reaction of the corresponding 3-alkyl-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones, {\bfseries 1,} with the appropriate aldehydes. 3-alkyl-4-insert ignore into journalissuearticles values(alkylamino);-4,5-dihydro-1H-1,2,4-triazol-5-ones of type {\bfseries 11-16} were synthesized from the selective reduction of compounds {\bfseries 5-10} with NaBH4 in diglyme or DMSO medium as a general and convenient method.
