Abstract

S - Carbethoxymethyl - 1 - phenyl - 3 - (1, 2, 4 - triazol-3-yl)-isothiourea is prepared by heating 3-amino-1,2,4-triazole with phenyl isothiocyanate in dry dioxane to give 1-phenyl-3-(3-triazolyl) thiourea, which is then refluxed with ethyl chloroacetate. Specifications 507,841, 531,246, 531,312, 547,064, 562,205, 592,672, 599,919, 613,400, 616,822, 651,749, 653,284, 655,082, 658,826, 680,593, 682,355, 748,750, 814,823, 861,194, 871,801 and 886,723 are referred to.
