Reaction Steps
5.0 g (0.018 mole) of N-(4,6-dimethyl-pyrimidin-2-yl)-2,5-dichloroaniline are dissolved in 100 ml of toluene and heated to reflux. A gentle stream of phosgene is then introduced for a period of 4 hours. The excess phosgene is blown out with nitrogen, and the toluene solution is washed cold with water, dried with magnesium sulfate and then concentrated by evaporation. 5.8 g (95.1%) of the title compound of formula ##STR20## are isolated in the form of crystals having a melting point of 121°-123° C.
