N-benzyl(4-(1,1′-biphenyl)-4-yl-1H-imidazol-2-yl)methanamine (1 g; 0.0024 mol; prepared according to experimental conditions analogous to the preceding examples and using the appropriate starting compounds and reaction products) was diluted in 15 ml dimethylformamide. Potassium carbonate (1 g; 0.0073 mol) was added at about 23° C. and then hexane bromide (0.34 ml; 0.0024 mol) was added quite slowly. The reaction mixture was brought around the temperature of about 70° C. for about 3 hours before being poured in icy water. The mixture was extracted with ethyl acetate and the organic phase washed with water. After drying over magnesium sulfate, the solvents were concentrated using a rotative evaporator. After purification over a silica column (eluent: ethyl acetate-heptane/7-3), a light yellow solid was obtained in the form of a glue (yield of 13%). Free base. Melting point: 120-122° C. MH+=424.3.
