How is 4-Chloro-N-(6-chloro-3-pyridinyl)benzamide (CAS: 325457-99-6) typically synthesized?

4-Chloro-N-(6-chloro-3-pyridinyl)benzamide (CAS: 325457-99-6) is typically synthesized via a multi-step process involving the condensation of 4-chlorobenzoic acid and 6-chloro-3-pyridylamine. The reaction is catalyzed by a mild coupling agent like HATU, and the process yields a high purity product with good selectivity. The reaction is carried out in a solvent such as DMF at room temperature, and the product is isolated by standard purification techniques.
