Reaction Steps

Using the procedure as described in example 1, cis-4-[4,5-bis-(4-chloro-phenyl)-2-(4,6-diethoxy-pyridin-3-yl)-4,5-dihydro-1H-imidazole was reacted with phosgene to give cis-4-[4,5-bis-(4-chloro-phenyl)-2-(4,6-diethoxy-pyridin-3-yl)-4,5-dihydro-imidazole-1-carbonyl chloride. The carbonyl chloride was then coupled with 2-piperazinone (Alfa) to give cis-4-[4,5-bis-(4-chloro-phenyl)-2-(4,6-diethoxy-pyridin-3-yl)-4,5-dihydro-imidazole-1-carbonyl]-piperazin-2-one hydrochloride.
