Reaction Steps
0.5 mL butyllithium (1.6 mol/L in THF) was added to 0.15 g 1,4-diphenyl-1H-imidazole in 10 mL THF at −78° C. under argon. The reaction was stirred 40 min at −78° C. and 0.22 g 2-bromo-1-(4-pyrimidin-2-yl-piperazin-1-yl)-ethanon was added to the reaction. After stirring 1 h at −78° C. the reaction was decomposed with saturated sodiumammoniumchloride solution. The mixture was extracted with ethyl acetate. The organic layer was dried and evaporated. The residue was purified by chromatography on Alox (gradient: dichlormethane/EtOAC/MeOH 9:2:0-50:45:5) to yield 20 mg of the desired compound. Rt: 1.13 (method B), (M+H)+: 425
