Abstract:2-(2-Chloromethyl phenyl)ethyl benzoate(3) was prepared from phenethyl alcohol via annelation and ring opening reaction, and the process was improved. Reaction conditions were optimized as follows: aqueous hydrochloric acid concentration 6 mol/L, n(formalin):n(benzoyl chloride):n(zinc chloride):n(1) =3.5:1.03:0.7:1, reaction time of annelation and ring opening was 13 h and 10 h, respectively. The target compound was obtained in 81.6% yield under optimized conditions, and its structure was confirmed by 1H NMR. The improved process shows a lower cost and is suitable for commercial production. |
Key words:2-(2-Chloromethyl phenyl)ethyl benzoate; phenethyl alcohol; process improvement |
