How is Methyl (2E)-[2-(bromomethyl)phenyl](methoxyimino)acetate (CAS: 133409-72-0) typically synthesized?

Methyl (2E)-[2-(bromomethyl)phenyl](methoxyimino)acetate is typically synthesized via a multi-step process involving the bromination of a phenylacetate followed by a Wittig reaction. The key steps include bromination of the phenyl group, followed by reaction with a methoxyimino compound to form the desired ester. Common catalysts and reagents include NBS (N-bromosuccinimide) and methoxyimino compounds. The overall yield is moderate to good, depending on the purity of starting materials and reaction conditions.
