EP-A 344 775 discloses a process for preparing 4-benzoyl-5-hydroxypyrazoles in one step where the synthesis is carried out starting from bromobenzenes and 5-hydroxypyrazoles in the presence of carbon monoxide, base and catalyst. The benzoyl radical of the target molecules may carry the following substituents in the 3-position: alkoxycarbonyl, alkoxy, alkoxymethyl. These substituents are considered to be relatively stable or inert chemically and allow the use of the drastic reaction conditions of the working examples. In contrast, the preparation of benzoyl-5-hydroxypyrazoles which carry less stable substituents in the 3-position, as is the case, for example, for the isoxazole or isoxazoline radical, are not described in EP 344 775, with respect to the drastic reaction conditions. In particular, owing to its redox properties, the isoxazole or isoxazoline radical is considered to be a highly sensitive radical. A further disadvantage of the process known from EP-A 344 775 is the fact that the 5-hydroxypyrazole is always employed in a large excess.
Below, the process is illustrated in more detail, using the example where R6=pyrazole (XI.a) as heterocycle. However, in principle, it is also possible to use other heterocyclic compounds, as defined at the outset.
The process is preferably carried out by reacting a hydroxypyrazole of the formula XI.a 
in which R7 is C1-C6-alkyl and M is hydrogen or an alkali metal atom, preferably sodium or potassium, and a bromobenzene of the formula X 
in which R1 to R5 are as defined above, in the presence of carbon monoxide, a palladium catalyst, if appropriate at least one molar equivalent of a potassium salt and if appropriate at least one molar equivalent of a tertiary amine of the formula XIII

 EP - A 344 775 discloses a process for preparing 4 - benzoyl-5 - hydroxypyrazoles in one footfall where the synthesis is carried out start from bromobenzenes and 5 - hydroxypyrazoles in the bearing of carbon monoxide, base and catalyst. The benzoyl extremist of the target molecules may have a bun in the oven the following substituents in the 3 - position: alkoxycarbonyl, alkoxy, alkoxymethyl. These substituents are considered to be relatively static or inert chemically and allow the use of the drastic chemical reaction conditions of the work examples. In line, the preparation of benzoyl-5 - hydroxypyrazoles which carry less stable substituents in the 3 - position, as is the lawsuit, for example, for the isoxazole or isoxazoline radical, are not described in EP 344 775, with respect to the drastic reaction condition. In particular, owing to its redox properties, the isoxazole or isoxazoline radical is considered to be a highly sensitive radical. A further disadvantage of the process known from EP - A 344 775 is the fact that the 5 - hydroxypyrazole is constantly employed in a large overindulgence.
