Reaction Steps

A mixture containing 2-(4-[1,1′-biphenyl]-4-yl-1H-imidazol-2-yl)ethylamine (obtained in Stage 32.2 of Example 32; 660 mg; 0.0025 mol) and n-butane sulphochloride (390 mg; 0.0025 mol) in 20 ml of DMF is stirred for two hours at 23° C. Potassium carbonate (345 mg; 0.0025 mol.) is then added, then stirring is continued for two hours. The solvent is evaporated off and the reaction mixture is taken up in water and dichloromethane. The organic phase is washed with a saturated solution of sodium chloride then dried. The solvent is evaporated off and the residue obtained is purified on a silica column (eluent: CH2Cl2-MeOH/93-07). A light beige-coloured powder is obtained with a yield of 19%. Melting point: 168.5° C.
