Versuchsvorschrift

To a solution of sodium hydroxide (100 g, 2.50 mol) in 1.8 L of a 10:8 mixture of water and methanol was added 4-hydroxyacetophenone (136 g, 1.00 mol). After stirring at room temperature for 30 minutes, 4-Methoxybenzaldehyde (136 g, 1.00 mol) was added to this mixture. The reaction mixture was stirred at 50° C. oil bath for 16 hours. A clear yellow solution resulted which was allowed to stir at room temperature for 30 minutes. 1N HCl aq (500 mL) and 600 mL of a 1:1 mixture of dichloromethane and THF were added to result two layers. The organic layer was washed by saturated NaHCO3 aq. (300 mL×2) and water (300 mL×3) and evaporated to yield orange solid. This solid was washed by 300 mL of EtOAc two times. The resulted yellow solid was dried in vacuo. Yield 133 g (52%). 1H NMR (CDCl3): δ3.85 (s, 3H), 6.93 (m, 4H), 7.47 (d, 1H), 7.50 (d, 2H), 7.75 (d, 1H), 7.96 (d, 2H).
