On March 23, 2022, Nokura, Yoshihiko; Tobita, Hidekatsu published a patent.SDS of cas: 1268137-13-8 The title of the patent was Heterocyclic compound, and pest control method. And the patent contained the following:
Disclosed is a pest control method, characterized by applying a compound I [R1 = alkyl, alkoxy, cyano, etc. (wherein alkyl and alkoxy are optionally substituted with halo); n = 0-2; Q = Q1 or Q2; X1 = CH or N; X4 = -CO2Me, -CONHCH3, -CO2Et, etc.; X3 = hydrocarbon chain, cyclopropyl, alkoxy, etc. (wherein hydrocarbon chain, cyclopropyl and alkoxy are optionally substituted with halo); R61 = Me or ethyl; J = J1 or J2; Y1 = oxygen atom, sulfur atom, -N(R2)-, etc.; Y2 = C(R6) or N; Y3 = C(R7) or N; Y4 = oxygen atom, sulfur atom or C(R8); R2, R8 = H, hydrocarbon group or cyclopropyl (wherein hydrocarbon chain and cyclopropyl are optionally substituted with halo); R6, R7 = alkyl, alkoxy, cyano, etc. (wherein alkyl and alkoxy are optionally substituted with halo); E = hydrocarbon chain (optionally substituted with group A), alicyclic hydrocarbon group (optionally substituted with group B), cyano, etc.; group A = halo, cyano, nitro, etc.; group B = oxo, thioxo, cyano, etc.; or its N-oxide or a salt thereof] to a harmful organism, a pest habitat area, a plant, or a plant cultivation carrier. Thus, compound II was prepared via reaction of 2-amino-3-bromophenol with benzoyl chloride, exposure to p-TsOH·H2O, Pd(dppf)Cl2-catalyzed reaction with bis(pinacolato)diboron, coupling reaction with Me 2-iodo-3-methoxyacrylate, and amidation with methylamine. A composition comprising an invention compound is useful for controlling Septoria tritici, Sphaerotheca fuliginea, Cladosporium fulvum, etc. The experimental process involved the reaction of 7-Bromo-2-phenylbenzo[d]oxazole(cas: 1268137-13-8).SDS of cas: 1268137-13-8
