The invention relates to a process for the preparation of 3-difluoromethyl-1 -methyl-1 H-pyrazole-4-carboxylic acid (9-dichloromethylene-1,2,3,4-tetrahydro-1,4-methano-naphthalen-5-yl)-amide by acylating the oxime oxygen of the compound of formula (VIII), in the presence of a solvent and an acylating agent of formula (XI) R1C(X)-CI (XI); wherein X is oxygen or sulfur; R1 is chloro if X is oxygen or sulfur; or R1 is C1-C6alkoxy, CH3-C(=CH2)-0-, phenoxy or trichloromethoxy if X is oxygen; and a) if R1 is chloro and the compound of formula (XI) was added to the compound of formula (VIII); reacting the so obtained product of formula (Xlla) wherein X is oxygen or sulfur; with the compound of formula (IX) b) if R1 is chloro and the compound of formula (VIII) was added to the compound of formula (XI); or R1 is C1-C6alkoxy, CH3-C(=CH2)-0-, phenoxy or trichloromethoxy if X is oxygen; reacting the so obtained product of formula (XII) wherein X is oxygen or sulfur; R1 is chloro if X is oxygen or sulfur; or R1 is C1-C6alkoxy, CH3-C(=CH2)-0-, phenoxy or trichloromethoxy if X is oxygen; with the compound of formula (IX).
该发明涉及一种制备3-二氟甲基-1-甲基-1H-吡唑-4-羧酸(9-二氯甲亚甲基-1,2,3,4-四氢-1,4-甲基-萘-5-基)-酰胺的方法,通过在溶剂和式(XI)R1C(X)-CI(XI)的酰化试剂存在下,酰化化合物的氧肟氧原子,所述化合物的分子式为(VIII),其中X为氧或硫;若X为氧或硫,则R1为氯;或者若X为氧,则R1为C1-C6烷氧基、CH3-C(=CH2)-0-、苯氧基或三氯甲氧基;a)若R1为氯且将式(XI)的化合物加入到式(VIII)的化合物中,则将所得的式(Xlla)的产物与式(IX)的化合物反应;b)若R1为氯且将式(VIII)的化合物加入到式(XI)的化合物中,或者若X为氧,则R1为C1-C6烷氧基、CH3-C(=CH2)-0-、苯氧基或三氯甲氧基,则将所得的式(XII)的产物与式(IX)的化合物反应。
