実験手順
In a manner analogous to the method described in example 3, rac-5-[(4S*,5R*)-4,5-bis-(4-chloro-phenyl)-4,5-dimethyl-4,5-dihydro-1H-imidazol-2-yl]-2-tert-butyl-4-ethoxy-N,N-dimethyl-benzenesulfonamide was reacted with phosgene in the presence of triethylamine to give rac-(4S*,5R*)-2-(4-tert-butyl-5-dimethylsulfamoyl-2-ethoxy-phenyl)-4,5-bis-(4-chloro-phenyl)-4,5-dimethyl-4,5-dihydro-imidazole-1-carbonyl chloride. The carbamoyl chloride was then reacted with 1-(3-methanesulfonyl-propyl)-piperazine dihydrochloride (prepared as described in Fotouhi, N. et al. WO 2005110996) in the presence of triethylamine 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 30% methanol in carbon dioxide). HR-MS (ES, m/z) calculated for C40H53N5O6S2Cl2 [(M+H)+] 834.2887, observed 834.2878.
