<p>N-Acylated isoureas prepn. cpd. (I) is reacted with cpd. (II) at -30 to +100 degrees C: (R = haloalkyl or an opt. substd. aromatic residue which is opt. bound to a heterocyclic residuef R1 = opt. substd. aliphatic-, aromatic- or heterocyclic residuef n = 0 or 1; x = 1, 2 or 3; X = halogen; R2 and/or R3 = H, opt. substd. aliphatic-, aromatic- or heterocyclic residues or R2 + R3 + N form a ring system which opt. contains further heteroatoms.</p> |
