HCID 177544015-{(4S,5R)-4,5-Bis-(4-chlorophenyl)-1-[4-(2-hydroxyethyl)piperazine-1-carbonyl]-4,5-dimethyl-4,5-dihydro-1H-imidazol-2-yl}-N-tert-butyl-2-chloro-4-ethoxybenzenesulfonamide

Procedure

In a manner analogous to the method described in example 5, rac-(4S*,5R*)-2-(5-tert-butylsulfamoyl-4-chloro-2-ethoxy-phenyl)-4,5-bis-(4-chloro-phenyl)-4,5-dimethyl-4,5-dihydro-imidazole-1-carbonyl chloride (example 45) was reacted with 2-piperazin-1-yl-ethanol (Chemical Dynamics) to give the title compound as a racemic mixture. The enantiomers were then separated by supercritical fluid chromatography (Berger Instrument Multi-Gram II, Daicel ChiralPak OD-H 3×25 cm, 35° C. at 100 bar, eluting with 25% methanol in carbon dioxide). HR-MS (ES, m/z) calculated for C36H45N5O5SCl3 [(M+H)+] 764.2202, observed 764.2198.
