Versuchsvorschrift

Butyllithium in hexane (1.6 M) (12.75 ml) was added dropwise at −20° C. under N2 to a solution of 6-bromo-4-(3-chlorophenyl)-2-methoxyquinoline (6.7 g) in THF (60 ml) and the mixture was stirred at −20° C. for 30 minutes. A solution of (1-butyl-1H-imidazol-5-yl)(4-chlorophenyl)methanone (3.35 g) in tetrahydrofuran (30 ml) was added at −20° C. under N2 and the mixture was stirred at room temperature for one night. Water was added and the mixture was extracted with ethyl acetate. The organic layer was dried, filtered off and evaporated. The residue was purified by column chromatography over silica gel (eluent: CH2Cl2/CH3/OH/NH4OH 97/3/0.1). The pure fractions were collected and evaporated, yielding 2.5 g (total 48%) of (±)-α-(1-butyl-1H-imidazol-5-yl)-4-(3-chlorophenyl)-a-(4-chlorophenyl)-2-methoxy-6-quinoline-methanol (interm. 2).
