Versuchsvorschrift

To a mixture of N-(4-acetyl-3-methylphenyl)acetamide (1.3 g, 7.0 mmol) and NaOH (1.4 g, 36 mmol) in 25 mL of absolute EtOH was added 4-hydroxy-3-methylbenzaldehyde (1.0 g, 7.3 mmol). The reaction mixture was stirred at room temperature for 18 hr. 5 mL of water was added and the reaction mixture was acidified with concentrated HCl to pH 5-6. The aqueous layer was extracted with two 25 mL portions of EOAc, and the layers were separated. The organic layer was dried with Na2SO4, filtered and concentrated under reduced pressure. The resulting product was submitted to the next step without further purification.
