How is tert-Butyl 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (CAS: 885693-20-9) typically synthesized?

The compound is typically synthesized via a Suzuki coupling reaction, where a pyridine derivative is coupled with a boronic acid derivative in the presence of a palladium catalyst and a base. The reaction conditions involve heating under argon atmosphere to ensure sterically unhindered access of the coupling partners. The yield is around 70-80%, and the reaction is selective for the desired product.
