Abstract
4-Trichlorophosphazopyrimidines or their hydrochlorides were obtained by the reaction between 4-aminopyrimidines and phosphorus pentachloride. Without separation, these compounds were converted into dichloranhydrides of the corresponding pyrimidyl-4-amidophosphoric acids of their hydrochlorides by the action of anhydrous formic acid.
