Benzoyl chloride → 2-Chloroethylbenzoate

참여 물질

반응 단계

20.0 g (142 mM) of benzoyl chloride and then additionally 14.4 g (142 mM) of triethylamine were added dropwise with vigorous stirring at room temperature to a solution of 11.5 g (142 mM) of chloroethanol in 200 ml of THF (exothermic reaction). After stirring for 1 h, the mixture was concentrated on a rotary evaporator, and the residue was partitioned between methylene chloride and water and acidified with 10% strength hydrochloric acid. The aqueous phase was reextracted twice with methylene chloride and the organic phase was then concentrated after drying with sodium sulfate. 26.0 g (99%) of 2-chloroethyl benzoate were isolated.
