Abstract:
The invention relates to a process for the preparation of a ketone of a general formula 1 with X being Cl or Br, in particular with X being Cl, with Y being F, Cl, Br, I or H, in particular with Y being F,comprising the steps of: activation of a carboxylic acid by using a peptide coupling agent, coupling of the activated carboxylic acid with a malonic acid derivative providing a β-ketoester precursor and converting the β-ketoester precursor to the ketone of the general formula 1.

Claim (Index 1):
A process for the preparation of a ketone of a general formula 1 with X being Cl or Br, in particular with X being Cl, comprising the steps of:\n a. reacting a carboxylic acid of a general formula 2 \n with a peptide coupling agent to yield an activated carboxylic acid,\n b. reacting the activated carboxylic acid with a malonic acid derivative, yielding a \u03b2-ketoester precursor, in particular a \u03b2-ketoester precursor of the general formula 6a or 6b, \n c. converting the \u03b2-ketoester precursor to the ketone of the general formula 1, wherein R 4  and R 6  independently of one another are H or C 1  to C 6  alkyl, R 5  is C 1  to C 6  alkyl, R 7  is C 1  to C 6  alkyl or a substituted or unsubstituted phenyl, in particular R 6  is C 1  to C 3  alkyl and R 7  is C 1  to C 3  alkyl, and Y is F, Cl, Br, I or H, in particular F.
