Reaction Steps

A solution of 6-hydroxybenzofuran-3(2H)-one (0.50 g, 3.3 mmol) and 2-methyl-1H-indole-3-carboxaldehyde (0.58 g, 3.6 mmol) in ethanol (10 mL) was added with concentrated hydrochloric acid (1.0 mL), and the mixture was stirred at 75° C. for 2 hours. The reaction mixture was cooled to room temperature, and then the solid was collected by filtration, and washed with methanol to obtain (Z)-6-hydroxy-2-[(2-methyl-1H-indol-3-yl)methylene]benzofuran-3(2H)-one (1.1 g, 95%).
