The present invention describes a process for preparing isoxazoles of the formula I where: R1is hydrogen, C1-C6-alkyl, R2is hydrogen, C1-C6-alkyl, R3, R4, R5are each hydrogen, C1-C6-alkyl or R4and R5together from a bond, R6is a heterocysclic ring, n is 0, 1 or 2; which comprises preparing an intermediate of the formula VI where R1, R3, R4and R5are each as defined above, followed by halogenation, thiomethylation, oxidation and acylation to give compounds of the formula I. Furthermore, the invention describes novel intermediates for preparing the compounds of the formula I and novel processes for preparing the intermediates.
