Abstract: The present invention relates to a method for precipitating/re-precipitating 2-chloronicotinic acid in an acidic medium. This method is characterised in that the 2-chloronicotinic acid is either a) precipitated from a solution that is susceptible of being alkaline in a mixture containing water and C3-C5 alcohol with the potential addition of an acid, or b) re-precipitated by heating in a mixture containing water and C3-C5 alcohol.

Abstract: The invention relates to a method for producing isoxazolene of the formula (I), where the substituents have the following meanings: R1 is hydrogen, C1-C6 alkyl, R2 is C1-C6 alkyl, R3, R4, R5 are hydrogen, C1-C6 alkyl or R4 and R5 together form a linkage, R6 is a heterocyclic ring, and n is 0, 1 or 2. Said method comprises the production of an intermediate compound of the formula (VI) where R1, R3, R4 and R5 have the meanings given above. This step is followed by halogenation, thiomethylation, oxidation and acylation to yield compounds of formula (I). The invention also relates to new intermediate products for producing compounds of formula (I) and new methods for producing the intermediate products.
