Reaction Steps

A solution of 820 mg 2-chloropyrimidine and 1.6 g cis-2,6-dimethylpiperazine in 25 mL toluene was heated at reflux temperature for 12 hours. The solvent was evaporated, the residue was basified with 5% sodium hydroxide and extracted with 2×100mL of dichloromethane. The combined organic extracts were dried over anhydrous sodium sulfate and concentrated to give cis-2,6-dimethyl-1-(2-pyrimidyl)-piperazine. This amine was then used to prepare 2-phenyl-4(5)-[(4-(2-pyrimidinyl)-cis-2,6-dimethylpiperazin-1-yl)-methyl]-imidazole (Compound 140), m.p. 130°-135° C., according to the procedures described in Example VIII.
