Disclosed is a method for preparing a compound of Formula 1
wherein
R1 is CHX2, CX3, CX2CHX2 or CX2CX3;
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.
本发明公开了一种制备式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,每个都可按本公开说明中定义的进行取代;包括在碱的存在下将式2化合物与氢氧化胺接触。本发明还涉及式2的新化合物,作为上述方法的起始材料而有用。
