How is 3-(4-(4-(2-(3-((dimethylamino)methyl)phenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)-1-ethyl-1H-pyrrolo[1,2-a]pyrimidin-2(3H)-yl)phenyl)-1,1-dimethylurea (CAS: 942918-07-2) typically synthesized?

The compound is synthesized through a multistep process involving the condensation of an ethyl pyrazole with a 2-(3-(dimethylamino)methyl)phenyl-1H-pyrrolo[2,3-b]pyridine derivative. This is followed by a coupling reaction with a 4-(4-(2-(3-((dimethylamino)methyl)phenyl)-1H-pyrrolo[2,3-b]pyridin-4-yl)-1-ethyl-1H-pyrrolo[1,2-a]pyrimidin-2(3H)-yl)benzaldehyde, using a palladium catalyst in the presence of a base. The final step involves the formation of the urea linkage.
