Versuchsvorschrift

To a solution of potassium hydroxide (0.67 g, 9.80 mmol) in ethanol (30 ml) is added 2-naphthol (1.41 g, 9.80 mmol) and 4-(2-bromoethoxy)benzaldehyde (2.25 g, 9.80 mmol). Then the mixture is heated to reflux for 8 hours. After cooled to −5° C., the precipitate is collected by filtration, washed with water, and dried under vacuum to give the title product (1.03 g, 36%).
