Title:
PREPARATION METHOD FOR PHENYLISOXAZOLINE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2022/002116
Kind Code:
A1
Abstract:
The present invention provides a synthesis method for a phenylisoxazoline compound, comprising: synthesizing uracil first by taking 2-fluoro-4-chloro-5-methylaniline as a starting raw material, and then synthesizing an isoxazoline ring to obtain a target compound, i.e., the phenylisoxazoline compound. The preparation method provided in the present invention can be widely used for synthesizing phenylisoxazoline containing uracil, and can greatly improve the yield, effectively reduce the cost, and facilitate industrial production.
