Versuchsvorschrift

A mixture of intermediate (20) (0.0245 mol), 2-phenyl-1H-imidazole (0.0368 mol) and K2CO3 (0.0735 mol) in acetonitrile (150n) was stirred at 60° C. The solvent was evaporated till dryness. The residue was taken up in DCM and water. The organic layer was separated, dried (MgSO4), filtered and the solvent was evaporated till dryness. The residue was purified by column chromatography over silica gel (eluent: CH2Cl2/CH3OH/NH4OH 97/3/0.1; 15–40 μm). The pure fractions were collected and the solvent was evaporated, yielding 0.8 g (5.1%) of ethyl 4-(3-chlorophenyl)-1,2-dihydro-2-oxo-6-[(2-phenyl-1H-imidazol-1-yl)(4-phenyl-2-thiazolyl)methyl]-3-quinolinecarboxylate.
