Patent ID: 7803941

Claim:
Process for preparing a compound of formula (I) in which A is N, D is N, E is CH, and X 1 is H, CN or F, by reacting a compound of the general formula (II) in which A is N, D is N, E is CH, X 2 is H, Cl, Br, I or CN and Hal is Cl, Br or I, with a fluoride in the presence of at least one compound of the general formula (III) in which A is a radical of the formulae (IV) or (V) and B, independently of A, is a radical of the formulae (IV), (V), (VIa) or (VIb) where the individual R 1 are the same or different and are each straight-chain or branched C 1 -C 10 -alkyl, straight-chain or branched C 2 -C 10 -alkylene or C 6 -C 12 -aryl, where one or more NR 1 R 1 groups may also be a 3- to 5-membered, saturated or unsaturated ring which is formed from one nitrogen atom and otherwise carbon atoms, where the formula (IV) and the group in formula (VIa) may also be a radical of a saturated or unsaturated 4- to 8-membered ring which contains two nitrogen atoms and otherwise carbon atoms, X is N or P and An Θ is one equivalent of an anion, characterized in that the reaction is effected in one stage.
