Reaction Steps
(4-[1,1′-biphenyl]-4-yl-1H-imidazol-2-yl)-N-methylmethanamine (1 g; 0.003 mol; prepared under experimental conditions similar to those previously and using suitable starting reagents and reaction products) is diluted in 20 ml of dimethylformamide. Potassium carbonate (1.23 g; 0.009 mol) is added at 23° C. then benzyl bromide (0.34 ml; 0.003 mol) is added fairly slowly. The reaction mixture is stirred at this temperature for 48 hours then poured in ice-cooled water. The mixture is extracted with ethyl acetate and the organic phase washed with water. After drying over magnesium sulphate, the solvents are concentrated using a rotary evaporator. After purification on a silica column (eluent: ethyl acetate-heptane/8-2), a white-coloured solid is obtained in the form of a paste (yield of 16%). Free base. Melting point: 106-108° C.
