    摘要: Preparation of an optically active alkamine in the sinister configuration, or a derivative of said alkamine, which is reacted with an 3-X-4-chloro(or RO- where R is hydrogen or an alkali metal)-1,2,5-thiadiazole to prepare S-3-X-4-(3-substituted amino-2-hydroxypropoxy)-1,2,5-thiadiazole beta adrenergic blocking agents. Novel 3-morpholino-4-chloro(or RO-)-1,2,5-thiadiazoles and their preparation also are described.

    摘要: 9-(Dihalobenzyl)adenines are prepared uncontaminated with other positional isomers in a series of mild transformations starting from 4,5,6-triaminopyrimidine and proceeding via 7-(N-formyl-N-dihalobenzyl)amino[1,2,5]thiadiazolo[3,4-d]pyrimidine. The resulting compounds have anticoccidial activity and are useful in controlling cecal and/or intestinal coccidiosis when administered in minor quantities to animals, in particular to poultry usually in admixture with animal sustenance.

    摘要: Fluorinated anilines, especially p-fluoroaniline and 2,4-difluoroaniline, are prepared by treating aromatic azides with anhydrous hydrogen fluoride. The aromatic azides, in turn, are prepared from the corresponding anilines by treatment with nitrous acid or salt thereof and an alkali metal azide in the presence of a mineral acid, and in an aqueous-nonaqueous, two-phase environment.
