Reaction Steps

cis-4,5-Bis-(4-chloro-phenyl)-2-[4-(1-diethylcarbamoyl-1-methyl-ethyl)-2-ethoxy-phenyl]-4,5-dihydro-imidazole-1-carbonyl chloride (27 mg, 0.0439 mmol) was reacted with 1-(2-methanesulfonyl-ethyl)piperazine dihydrochloride (17.5 mg, 0.0659 mmol, example 17) using the procedure described in example 25 to give cis-2-(4-{4,5-bis-(4-chloro-phenyl)-1-[4-(2-methanesulfonyl-ethyl)-piperazine-1-carbonyl]-4,5-dihydro-1H-imidazol-2-yl}-3-ethoxy-phenyl)-N,N-diethyl-isobutyramide (29.5 mg, 87% yield) as white solids. HR-MS (ES, m/z): observed 770.2909, calculated for C39H50Cl2N5O5S [(M+H)+] 770.2904.
