Participants

Reaction Steps

In a manner analogous to the method described in example 3, rac-(4S*,5R*)-2-(2-tert-butyl-4-ethoxy-pyrimidin-5-yl)-4,5-bis-(4-chloro-phenyl)-4,5-dimethyl-4,5-dihydro-imidazole-1-carbonyl chloride was reacted with 1-[2-(2-hydroxyethoxy)-ethyl]-piperazine (Aldrich) 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 C36H46N6O4Cl2 [(M+H)+] 697.3031, observed 697.3026.
