Abstract:Methyl acetimidate hydrochloride and 2,4-dichlorophenylhydrazine serve as raw materials to compound 2-(2,4-dichlorophenyl)hydrazidethaneimidic acid by the reagent triethylamine.And then react with phosgene to get 4,5-dihydro-3-methyl-1-(2,4-dichlorophenyl)-1,2,4-triazol-5-(1H)-one by cyclization reaction.As a result,the total yield of synthesized was 90.6%(2,4-dichlorophenylhydrazine as the standard) and purity of product was 98.9%.
