Reaction Steps
A solution of 5-hydroxy-2,3-dihydro-1H-inden-1-one (0.30 g, 2.0 mmol) and 1H-indole-3-carboxaldehyde (0.32 g, 2.2 mmol) in methanol (10 mL) was added with 50% sodium hydroxide (0.34 mL), and the mixture was stirred at 50° C. for 2 hours. The reaction mixture was cooled to room temperature, and then added with water, and the precipitated solid was collected by filtration, and washed with methanol to obtain (E)-2-[(1H-indol-3-yl)methylene]-5-hydroxy-2,3-dihydro-1H-inden-1-one (0.45 g, 83%).
