rac-5-[(4S*,5R*)-4,5-bis-(4-chloro-phenyl)-4,5-dimethyl-4,5-dihydro-1H-imidazol-2-yl]-2,4-dimethoxy-pyrimidine was converted to the corresponding carbonyl chloride using phosgene and triethylamine in a manner similar to example 2. The carbonyl chloride was then reacted with 4-[3-(methylsulfonyl)propyl]-piperazine (prepared as described in Fotouhi, N. et al. WO 2005110996) following the synthetic procedure as described in example 3 to give the title compound. HR-MS (ES, m/z) calculated for C32H38N6O5SCl2 [(M+H)+] 689.2074, observed 689.2072.
