Procedure

A mixture of 4-pyridin-4-yl-1,3-dihydroindol-2-one (50 mg, 0.24 mmol), 5-methyl-3H-imidazole-4-carbaldehyde (24.4 mg, 0.24 mmol) and piperidine (1 drop) in ethanol (2 mL) was stirred at room temperature for 2 days. The precipitate which formed was filtered. Crystals which formed in the filtrate were isolated, washed with ethanol and dried to give 7.8 mg of the title compound.
