Triethylamine → 2-Bromoethyl methacrylate

Participants

Reaction Steps

A reactor was charged with 12.50 g (100 mmol) of 2-bromoethanol and 100 ml of tetrahydrofuran (THF) at 0° C. in a nitrogen atmosphere. After the dropwise addition of 10.45 g (100 mmol) of methacrylic chloride and 11.13 g (110 mmol) of triethylamine, the mixture was reacted at 25° C. for 30 minutes with stirring. After completion of the reaction, the reaction mixture was concentrated under reduced pressure, and the residue was purified by distillation to obtain 17.30 g of 2-bromoethyl methacrylate shown by the following formula (M-20′) (yield: 90%).
