2-Phenoxyethyl bromide is used in the synthesis and antihypertensive activity of 4'-substituted spiro[4H-3,1-benzoxazine-4,4'-piperidin]-2(1H)-ones.
2-Phenoxyethyl bromide is synthesized by the reaction of phenol and dibromoethane. Put phenol, dibromoethane and sodium hydroxide in a reaction pot and stir and mix, react at 110 °C for 6 hours, recover dibromoethane, the recovery amount is about 60%, wash with 5% sodium hydroxide solution and water, and divide Take the oil layer, distill under reduced pressure, and collect the fractions at 130-150°C (6.7kPa) to obtain (2-bromoethoxy)benzene.
