Preparation of amidoalkylmelamines and aminoalkylmelamines of the formula I ##STR1## where R.sup.1 is an amidoalkyl group --(CH.sub.2).sub.n --NHZ or an aminoalkyl group --(CH.sub.2).sub.n --NH.sub.2, n is from 2 to 10, preferably from 2 to 6, Z is an amino protective group and R.sup.2 and R.sup.3 independently of one another are each hydrogen or have the same meanings as R.sup.1, are prepared by a process in which a chlorotriazine is reacted with a diamine of the formula H.sub.2 N--(CH.sub.2).sub.n --NHZ, where n and Z have the above meanings, to give an amidoalkylmelamine, and, if required, the group Z is eliminated.
公式I的amidoalkylmelamines和aminoalkylmelamines的制备方法
R1为amidoalkyl基团--(CH2)n--NHZ或aminoalkyl基团--(CH2)n--NH2,n为2至10,优选为2至6,Z为氨基保护基团,R2和R3独立地为氢或具有与R1相同的含义。该方法通过将三氯氮杂环与公式H2N-(CH2)n-NHZ的二胺反应来制备amidoalkylmelamine,如果需要,则消除Z基团。
