1-(4-Phenoxyphenyl)-1,3,5-triazines of the formula: ##SPC1## Or pharmaceutically acceptable nontoxic salts thereof are produced by reacting a urea or thiourea derivative of the formula: ##SPC2## With a carbonylisocyanate of the formula: ##EQU1## to produce a 1-(4-phenoxyphenyl)-1,3,5-triazine as above defined wherein R.sup.11 is hydrogen, and when a 1-(4-phenoxyphenyl)-1,3,5-triazine as above defined wherein R.sup.11 is alkyl is desired, reacting the triazine wherein R.sup.11 is hydrogen with a compound of the formula (alk).sub.n Y. The above defined triazines and their salts are useful as agents against protozoan infections and are particularly useful against coccidiosis.
式为1-(4-苯氧基苯基)-1,3,5-三嗪,或其药学上可接受的无毒盐,通过将式为的脲或硫脲衍生物与式为的羰基异腈反应制得:其中R.sup.11为氢,当需要制备其中R.sup.11为烷基的1-(4-苯氧基苯基)-1,3,5-三嗪时,将R.sup.11为氢的三嗪与式为(烷基).sub.n Y的化合物反应。上述定义的三嗪及其盐可用作抗原虫感染剂,特别适用于抗球虫病。
