  <I> Aas f </I> ührwngsbeispiel: An intimate mixture of 31.5 g of p-succinylamino - benzene - sulfonylbo ^ uanidine and 35 g of acetylacetane is stirred in a pressure vessel for 3 hours to 140 to 160 '</B> C heated. Then the excess Acetylaeeton is distilled off and the residue from 6 n.

   Acetic acid recrystallized. Yield: 35 g or 92.69o 'd. The 2- (p-N4-succinylamino, -benzene-sulfonylamino) -4, 6- dimethyl-pyrimidine obtained in this way shows, in accordance with the literature, a melting point (and decomposition) of 226 C.
