Versuchsvorschrift
A mixture of 5-bromo-1,3-dihydro-2H-indol-2-one (0.3 g, 1.41 mmol) (Starting Material 6), and excess 4-methyl-5-imidazolecarboxaldehyde (0.25 g, 2.27 mmol) (Aldrich) in 1% piperidine in 2-propanol (6 mL) was heated at 90° C. for 4 h. Hot water (6 mL) was added. On cooling, the crystallized product was filtered off, washed with aqueous 2-propanol and dried. (Yield 0.44 g, 100%)
