Zusammenfassung:	A process for the preparation of a compound of the general formula I is described according to which a compound of the general formula IIb is reacted with a compound of formula III L - R - S - R (III) in which L represents a leaving group, generally carrying out the reaction in the presence of a base. R represents an alkylene, alkenylene or alkynylene group, having from 1 to 4 carbon atoms, and R represents a heterocyclic group having a five-membered or 6-membered ring with 1 to 4 heteroatoms, selected from oxygen sulfur and nitrogen, and being linked to the adjacent sulphur atom via a ring carbon atom.
