Reaktionsschritte
A solution of 25.3 g of 4-(2,4-dichlorobenzyl)-phenol and 15.2 g of α-bromopropionic acid amide in 100 ml of dimethyl formamide was stirred for 2 hours at 100° C together with 16 g of potassium carbonate. After cooling, the reaction mixture was poured into 1 liter of water. A viscous oil precipitated which was absorbed in methylene chloride and washed with water. After drying over sodium sulfate, the solvent was distilled off under reduced pressure. The remaining colorless crystals were recrystallized from methanol. Yield: 25.8 g; melting point 148° - 149° C. ##STR5##
