Reaktionsschritte
Anhydrous potassium carbonate (14.9 g, 0.12 mol) was added to a mixture of 4-propylphenol (13.6 g, 0.10 mol) and 4-fluorobenzaldehyde (12.4 g, 0.10 mol) in N,N-dimethylacetamide (100 mL) under argon. The heterogeneous mixture was brought to reflux, maintained at that temperature for 5 h, then cooled to RT. Water (100 mL) and CH2Cl2 (100 mL) were added, resulting in a tri-phase system. The bottom layer was removed; the middle layer was dried over MgSO4 ; and, the top layer was extracted with CH2Cl2 (100 mL) and dried over MgSO4. The dried layers were combined and concentrated in vacuo at 50° C. to give an orange oil. The crude product was purified by distillation to give title compound (16.6 g, 69%) as a colorless oil. bp 133°-50° C. (0.2 mm Hg)
