실험 절차

To a solution of 1,3-dihydro4-fluoro-5-nitro-2H-indol-2-one (1 g, 5 mmol) in MeOH (10 mL) (Starting Material 10), was successively added, at r.t., 4-methyl-5-imidazolecarboxaldehyde (612 mg, 5.5 mmol) (Aldrich) and tetrabutyl ammonium hydroxide (11 mL, 1.0 M solution in MeOH)(Aldrich). The mixture was stirred at r.t. for 4 h. The resulting greenish precipitate was collected by suction filtration, washed with ether and air dried to yield (Z)-1,3-dihydro-4-fluoro-3-[(4-methyl-1H-imidazol-5-yl)methylene]-5-nitro-2H-indol-2-one as a green powder. (Yield 1.14 g, 79%).
