| titleOfInvention | Process for the preparation of phenyl substituted 3-difluoromethyl-1-methyl-1h-pyrazole-4-carboxylic acid n-methoxy-[1-methyl-2-phenylethyl] amides |
| abstract | The present invention relates to a process for the preparation of compounds of formula (I) wherein R 1 , R 2 and R 3 are as defined in claim 1, which process comprises a) a compound of formula (II) in the presence of an inert organic solvent Adding to a mixture comprising an organic nitrite of formula III (R 4 -ON = 0, wherein R 4 is C 1 -C 8 alkyl), a compound of formula IV and an inert organic solvent, b) Reacting the resulting compound of formula V with H 2 NO—CH 3 to produce a compound of formula VII, c) reducing the compound of formula VII to a compound of formula VIII, and d) reducing the compound of formula VIII the compounds of formula IX (wherein, R * is halogen, hydroxy or C 1 - 6 alkoxy) comprises the step of generating a compound of formula (I) by the reaction. [Formula I] [Formula II] [Formula IV] [Formula V] [Formula VII] [Formula VIII] [Formula IX] |
