How is N-{3-[2-(Dimethylamino)ethoxy]-4-methoxyphenyl}-2'-methyl-4'-(5-methyl-1,2,4-oxadiazol-3-yl)-4-biphenylcarboxamide (CAS: 170230-39-4) typically synthesized?

This compound is typically synthesized via a multistep process involving the formation of an oxadiazole ring and coupling with a biphenyl derivative. Commonly, the synthesis involves the use of catalytic amounts of palladium in the presence of a ligand, followed by coupling with an appropriate amino-containing compound. The overall yield is around 70-75%.
