Procedure
A mixture of 6-[chloro-3-furanyl(1-methyl-1H-imidazol-5-yl)methyl]-4-(3-chlorophenyl)-1-methyl-2(1H)-quinolinone (obtained in stage b) (0.0045 mol) in THF (30 ml) was cooled to 5° C. 2-Propanol-NH3 saturated (30 ml) was added dropwise quickly. The mixture was stirred at room temperature for 1 hour. The solvent was evaporated till dryness. The residue was taken up in DCM and water and the mixture was decanted. The organic layer was dried (MgSO4), filtered and the solvent was evaporated till dryness. The residue (2.2 g) was purified by column chromatography over silica gel (eluent: toluene/2-propanol/NH4OH 85/13/1; 15–40 μm). The pure fractions were collected and the solvent was evaporated. The residue was crystallized from CH3CN and DIPE. The precipitate was filtered off and dried, yielding 0.55 g (27.5%) of (±)-6-[amino-3-furanyl(1-methyl-1H-imidazol-5-yl)methyl]-4-(3-chlorophenyl)-1-methyl-2(1H)-quinolinone, melting point 197° C.
