该中间体在本合成路线中的序号：(VIII)Metalation of 1-trityl-4-iodoimidazole (VI) with ethylmagnesium bromide, followed by addition to 4-cyanobenzaldehyde (VII) gives rise to the carbinol (VIII), which is further reduced to the diaryl methane (IX) employing triibutyltin hydride in the presence of AIBN. Trimethylaluminium-catalyzed coupling between nitrile (IX) and amine (V) provides amidine (X). The N-trityl group of (X) is finally removed under acidic conditions to furnish the title compound.
