Reaction Steps

A solution of morpholin-4-yl-2-piperazin-1-yl-ethanone (17 mg, 0.081 mmol, Oakwood Products) and diisopropylethylamine (10 mg, 0.077 mmol) in 0.5 mL of methylene chloride was added to a solution of (4S,5R)-4,5-bis-(4-chloro-phenyl)-2-(4-cyano-2-ethoxy-phenyl)-4,5-dihydro-imidazole-1-carbonyl chloride (35 mg, 0.070 mmol, example 29) in 0.5 mL of methylene in a 4-mL vial. The vial was then capped and shaken for 1 h at room temperature. The reaction mixture was diluted with 1 mL of methylene chloride and 1 mL of water. The vial was agitated and centrifuged. The organic layer was transferred to a 4-mL vial and concentrated in vacuo. The crude was dissolved in 0.5 mL of acetonitrile, and then 0.6 mL of water and 0.492 mL of 0.5 M hydrochloric acid (2.46 mmol) were added to the sample. The sample was frozen with liquid nitrogen and lyophilized to give 4-{(4S,5R)-4,5-bis-(4-chloro-phenyl)-1-[4-(2-morpholin-4-yl-2-oxo-ethyl)-piperazine-1-carbonyl]-4,5-dihydro-1H-imidazol-2-yl}-3-ethoxy-benzonitrile hydrochloride (47.6 mg, 91% yield). LC-MS: 675.3 [(M+H)+].
