Heterocyclyclarbonyl substituted benzofuranyl-ureas of formula (I) are prepared by reacting heterocyclylcarbonyl substituted 3-amino-benzofuranes with appropriate isocyanates or isothiocyanates. The unsubstituted ureas are transferred into substituted ureas by usual methods of substitution. The heterocyclylcarbonyl substituted benzofuranyl-ureas are useful as active ingredients in medicaments particularly for the treatment of acute and chronical inflammatory processes.
A, D, L, R1, R2, R3, R4 are as defined in the applications, R4 being a heterocyclic group.
