Procedure

4-(Piperazine-1-sulfonyl)-morpholine hydrochloride (0.042 mmol) was suspended in methylene chloride, and 400 uL of diisopropylethylamine was added. The mixture was added to 4,5-bis-(4-chloro-phenyl)-2-(2-ethoxy-4-trifluoromethyl-phenyl)-4,5-dihydro-imidazole-1-carbonyl chloride (10 mg, 0.019 mmol, example 3), and the reaction mixture was allowed to stand overnight. It was diluted with methylene chloride and washed with water. The organic layer was evaporated, and the residue purified by flash chromatography using ethyl acetate and hexanes to give [4,5-bis-(4-chloro-phenyl)-2-(2-ethoxy-4-trifluoromethyl-phenyl)-4,5-dihydro-imidazol-1-yl]-[4-(morpholine-4-sulfonyl)-piperazin-1-yl]-methanone (9.0 mg). LR-MS: 740.2 [(M+H)+].
