How is 3-Cyclopropyl-1-(2-fluoro-4-iodophenyl)-6,8-dimethyl-2,4,7-trioxo-1,2,3,4,7,8-hexahydropyrido[2,3-d]pyrimidin-5-yl 4-methylbenzenesulfonate (CAS: 871700-32-2) typically synthesized?

This compound is typically synthesized via a multi-step process involving the protection of the cyclopropyl group, followed by the installation of the fluoro-iodophenyl moiety using a palladium-catalyzed coupling reaction. Additional steps include the introduction of the dimethyl group and the formation of the pyrimidine ring. The yield is generally moderate (50-70%), and the process requires careful control of reaction conditions to ensure high selectivity.
