Abstract
The reaction of 2-aminopyridines with PCl5 proceeds with the formation of 2-trichlorophosphazopyridines, which when treated with morpholine are converted to 2-dimorpholidochlorophosphazopyridines. By heating these last products with 96% ethanol, dimorpholido pyridyl-2-amidophosphoric acids are obtained.
