Patent ID: 7154006

Claim:
A process for preparing a compound(s) of the formula (I) in which m is an integer in the range from 0 to (5-n-p) n is 1, 2, 3 or 4 and p is 0, 1 or 2, where the sum of n+p is a maximum of 4 and R 1 is in each case independently hydrogen, fluorine, C 1 –C 12 -alkyl, C 5 –C 14 -aryl, C 6 –C 15 -arylalkyl, C 1 –C 12 -fluoroalkyl, C 1 –C 12 -fluoroalkylthio, C 1 -C 12 -fluoroalkoxy, C 1 –C 12 -alkylsulphonyl or radicals of the formulae (IIa) to (IIf) A-CN (IIa) A-CON(R 2 ) 2 — (IIb) A-CO 2 R 2 (IIc) A-CONH 2 (IId) A-COHal 2 (IIe) A-B—R 2 (IIf) where, in the formulae (IIa) to (IIf), A is absent or is a C 1 –C 8 -alkylene or C 1 –C 8 -fluoroalkylene radical and B is oxygen or NR 2 , and R 2 is in each case independently C 1 -C 8 -alkyl, C 6 –C 15 -arylalkyl or C 5 –C 14 -aryl, or C 5 –C 14 -aryl, or N(R 2 ) 2 as a whole is optionally a cyclic amino radical having a total of 4 to 12 carbon atoms and Hal 1 is chlorine or bromine, comprising: in a step A), converting a compound(s) of the formula (III) in which R 1 , Hal 1 , m, p and n are each as defined above in the presence of ionic fluoride to a compound(s) of the formula (IV) and, in a step B), converting the compound(s) of the formula (IV) to the compound(s) of the formula (I) with a reducing agent.
