| titleOfInvention | Novel Process for Preparation of Herbicidal Pyrimidyloxybenzoic Acid Oxime Esters |
| abstract | The present invention relates to substituted 5- (4,6-dimethoxypyrimidin-2-yl) oxy-4H- (1,3) -benzodioxin-4-one derivative of the general formula (IV) in the first step. Is reacted with an oxime of formula (III) or a metal salt thereof, and the compound of formula (V) produced in the second step is reacted with a pyrimidine derivative of formula (VI). It relates to a method for producing an oxime ester derivative of 2,6-di (4,6-dimethoxypyrimidin-2-yl) oxybenzoic acid.n n n n n n n n Wherein R 1 is hydrogen, halogen, cyano, nitro, C 1 -C 4 alkyl, C 3 -C 6 cycloalkyl, C 1 -C 4 alkoxy, C 2 -C 4 alkenyloxy, C 1 -C 4 alkylthio, amino, aryl, aryloxy, C 1 -C 4 acyloxy which may be substituted by C 1 -C 4 alkyl, n represents an integer from 1 to 5, R 2 is hydrogen, halogen, Cyano, nitro, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, C 1 -C 4 alkylthio, C 1 -C 4 alkoxycarbonyl, C 2 -C 4 alkenyloxycarbonyl, arylmethoxy Carbonyl, heteroarylmethoxycarbonyl, C 1 -C 4 alkylaminocarbonyl, arylmethylaminocarbonyl, heteroarylmethylaminocarbonyl, or aryl, R 3 and R 4 are each independently hydrogen, C 1- C 4 alkyl, C 1 -C 2 haloalkyl having 1 to 5 halogen atoms, or 1 to 5 halogen atoms and / or C 1 -C 4 alkyl, C 1 -C 4 alkoxy, C 1 -C during 2 haloalkyl and nitro It represents phenyl, which may contain one or two groups selected, or, R 3 and R 4 together with 1 to 5 halogen atoms and / or C 1 C 2 -C 6 alkylene chain which may be substituted by -C 4 alkyl R represents hydrogen or an alkali metal cation and Z represents halogen, C 1 -C 4 alkylsulfonyl or arylsulfonyl. |
