In a manner analogous to the method described in example 5, rac-(4S*,5R*)-4,5-bis-(4-chloro-phenyl)-2-[4-(1,1-dimethyl-2-oxo-propyl)-2-ethoxy-phenyl]-4,5-dimethyl-4,5-dihydro-imidazole-1-carbonyl chloride was reacted with 1-(1,1-dioxo-tetrahydro-2H-thiopyran-4-yl)-piperazine dihydrochloride (example 22) to give the title product 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 35% methanol in carbon dioxide). HR-MS (ES, m/z) calculated for C40H49N4O5SCl2 [(M+H)+] 767.2795, observed 767.2790.
