On July 9, 1998, Kanno, Hisashi; Kanda, Yoichi; Sunagawa, Kazuhiko; Eizuka, Takayoshi published a patent.SDS of cas: 170235-18-4 The title of the patent was Preparation of phenoxypicolinic acid derivatives as agrochemical fungicides. And the patent contained the following:
The title compounds [I; R = halo, C1-4 alkyl, haloalkyl, alkoxy, haloalkoxy, alkylthio, or alkylamino, etc.; n1 = 1-3; Y = C1-4 alkyl, haloalkyl, alkoxy, or haloalkoxy, etc.; m = 0-5] are prepared I are useful as active ingredients contained in agricultural or horticultural fungicides. Thus, 2-bromo-4-methoxy-6-[3-(trifluoromethyl)phenoxy]pyridine (preparation given) was treated with n-BuLi, reacted with CO2, and treated with 1N HCl to give 30% I (Rn1 = 4-OMe, Ym = 3-CF3), which at 1 kg/ha showed > 70% fungicidal effect for Botrytis cinerea. The experimental process involved the reaction of Methyl 6-bromo-5-methoxypicolinate(cas: 170235-18-4).SDS of cas: 170235-18-4
