The invention relates to new isopropylamino pyrimidine halogeno derivatives of the formula: <IMAGE> in which X represents a fluorine, a chlorine or a bromine atom. These compounds, when X stands for chlorine or bromine, are prepared by reacting, at room temperature and in stoichiometric proportions, 2-isopropylamino pyrimidine on the appropriate N-halogeno succinimide, in the presence of acetic acid.
