Reaktionsschritte

6.1 g of 4-hydroxybenzaldehyde, 7 g of ethyl α-chloropropionate, 4 g of sodium carbonate, 0.2 g of potassium iodide and 20 g of dimethyl formamide, were mixed, and the mixture was stirred at 100° C. for 5 hours and then cooled to room temperature. The inorganic salts were filtered off, and the residue was washed with dimethylformamide. The solution from the washing was combined with the filtrate, followed by concentration and distillation under reduced pressure, whereby 10.3 g of ethyl 2-(4-formylphenoxy)propionate was obtained as a colorless transparent liquid. The boiling point was from 130° to 140° C./1 mmHg.
