;
each X is independently Cl or F;
Z is optionally substituted phenyl; and
Q is phenyl or 1-naphthalenyl, each optionally substituted as defined in the disclosure;
comprising contacting a compound of Formula 2
with hydroxylamine in the presence of a base.
The present invention also relates to novel compounds of Formula 2, useful as starting materials for the aforedescribed method.
揭示了一种制备公式1化合物的方法,其中R1为CHX2,CX3,CX2CHX2或CX2CX3;每个X独立地为Cl或F;Z为可选取代的苯基;Q为苯基或1-
萘基,每个均可按照本公开说明中定义进行取代;包括在碱的存在下将公式2化合物与
羟胺接触。本发明还涉及公式2的新化合物,可用作上述方法的起始材料。
