Diisopropylethylamine → [4,5-Bis-(4-chloro-phenyl)-2-(2-ethoxy-4-trifluoromethyl-phenyl)-4,5-dihydro-imidazol-1-yl]-[4-(propane-2-sulfonyl)-piperazin-1-yl]-methanone

Participants

Reaction Steps

1-(Propane-2-sulfonyl)-piperazine (0.0286 mmol) was dissolved in 0.25 mL of methylene chloride and added to a solution of 4,5-bis-(4-chloro-phenyl)-2-(2-ethoxy-4-trifluoromethyl-phenyl)-4,5-dihydro-imidazole-1-carbonyl chloride (0.024 mmol, example 3) and diisopropylethylamine (0.072 mmol) in. 25 mL of methylene chloride in a 4 mL vial. The vial was capped and shaken overnight 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 to give [4,5-bis-(4-chloro-phenyl)-2-(2-ethoxy-4-trifluoromethyl-phenyl)-4,5-dihydro-imidazol-1-yl]-[4-(propane-2-sulfonyl)-piperazin-1-yl]-methanone. LR-MS (M+H)+=697.4.
