Versuchsvorschrift

A heterogeneous mixture of 4-chlorophenol (14.1 g, 0.11 mmol), 4-fluorobenzaldehyde 12.4 g, 0.1 mmol) and Cs2CO3 (65.0 g, 0.20 mmol) in DMF (400 mL) was stirred at 90° C. for 6 h. The reaction mixture was poured into water (1.2 L) and extracted with ethyl acetate (2×200 mL). The organic phase was washed with water (2×100 mL), dried and concentrated to give essentially pure 4-chlorophenoxybenzaldehyde, which was used directly for the next step.
