How is 4-((3-Chloro-4-methoxybenzyl)amino)-2-(methylthio)pyrimidine-5-carboxylic acid (CAS: 330786-34-0) typically synthesized?

This compound can be synthesized via a multistep process involving the condensation of an amino benzyl derivative with a chloro pyrimidine carboxylic acid followed by an alkylation step. The synthesis typically uses sodium hydride as a base and dimethyl sulfate as the alkylating agent. The yield is moderate, and the procedure involves careful handling of amines and haloarenes to ensure high purity and selectivity.
