以甲基芳烃（１ａ～１ １）经溴化、缩合得苄氧乙酸乙酯（４ａ～４ １），再经醇解、成盐得一系列苄氧乙酸２－二烷基氨基乙酯盐酸盐。药理实验表明（１ａ～１ｌ、２ｃ、２ｆ、２ｈ、２ｌ）具有很强的小鼠学习记忆促进作用 Methyl aromatic hydrocarbon (1a ~ 1 1) was brominated and condensed to give ethyl benzyloxyacetate (4a ~ 4 1). After alcoholysis, a series of benzyloxyacetic acid 2-dialkylaminoethyl ester salt Acid salt. Pharmacological experiments show (1a ~ 1l, 2c, 2f, 2h, 2l) has a strong role of learning and memory in mice
