Reaction Steps
A mixture of 4-pyridin-4-yl-1,3-dihydroindol-2-one (50 mg, 0.24 mmol), 4-oxo-2,4,6,7-tetrahydropyrano[3,4-c]pyrrole-1-carbaldehyde (39.2 mg, 0.24 mmol) and piperidine (1 drop) in ethanol (2 mL) was stirred at room temperature for 48 hours. The precipitate which formed was collected by vacuum filtration, washed with ethanol and dried to give 15 mg (17%) of the title compound.
