Procedure

Iodomethane (1.4 ml) was added to a mixture of (±)-6-[(4-chlorophenyl)-1H-imidazol-4-ylmethyl]-1-methyl-4-phenyl-2(1H)-quinolinone (7.5 g) and benzyltriethylammonium chloride (2 g) in THF (75 ml) and sodium hydroxide (75 ml) and the mixture was stirred at room temperature for 1 hour. Water was added and the mixture was extracted with ethyl acetate. The organic layer was dried, filtered off and evaporated till dryness. The residue was purified by column chromatography over silica gel (eluent: CH2Cl2/CH3OH/NH4OH 98.5/1.5/0.1). The pure fractions were collected and evaporated. Fraction 1 (3.5 g) was recrystallized from diethyl ether, yielding 3.3 g (42%) of (±)-6-[(4-chlorophenyl)(1-methyl-1H-imidazol-4-yl)methyl]-1-methyl-4-phenyl-2(1H)-quinolinone; mp. 149.9° C. (comp. 44). Fraction 2 was recrystallized from 2-propanone, methanol and diethyl ether, yielding 1.6 g (20%) of (±)-6-[(4-chlorophenyl)(1-methyl-1H-imidazol-5-yl)methyl]-1-methyl-4-phenyl-2(1H)-quinolinone (comp. 2, mp. 96.8° C.).
