Versuchsvorschrift

Air was bubbled in a mixture of 4-(3-chlorophenyl)-6-[(4-chlorophenyl)(4-methyl-4H-1,2,4-triazol-3-yl)methyl]-1-methyl-2(1H)-quinolinone (see Example B7) (0.0018 mol) in N,N-dimethylformamide (8 ml) at 5° C. for 30 minutes. 2-methyl-2-propanol, potassium salt (0.0036 mol) was added portionwise. The mixture was stirred at room temperature for 1 hour, poured out into water, filtered and washed several times with water. The precipitate was taken up in CH2Cl2. The organic layer was separated dried (MgSO4), filtered and the solvent was evaporated till dryness. The residue (1.1 g) was purified by column chromatography over silica gel (eluent: CH2Cl2/CH3OH/NH4OH 92/8/0.1; 15–40 μm). The pure fractions were collected and the solvent was evaporated. The residue (0.75 g, 85%) was crystallized from 2 propanone/DIPE. The precipitate was filtered off and dried, yielding 0.68 g (77%) of 4-(3-chlorophenyl)-6-[(4-chlorophenyl)hydroxy(4-methyl-4H-1,2,4-triazol-3-yl)methyl]-1-methyl-2(1H)-quinolinone, mp. 182° C.
