Followed the whole reaction process by T. L. C. (Thin Layer Chromatography), 1 , 2 dimethyl indole was synthesised by N-alkylated method of 2-methyl indole. using terra butylammontum tromide as phase transfer catalyst and dimethyl sulfate as alkylating agent.The component of the successful developing agent used in this paper is: peroloum (?) form: acetone = 20:9:1 (volume ratio). The amounts of the alkylating agent and the phase transfer catalyst effected on the yields of the products were investigated. The time which is necessary for the reaction were obtained by T. L. C. . The better synthetic conditions of 1,2- dimethyl indole wen; in quired through all the experiments.

本文以四丁基溴化铵为相转移催化剂、硫酸二甲酯为烷基化剂,通过2-甲基吲哚进行N-甲基化,合成1,2-二甲基吲哚,并用T. L. C. (Thin Layer Chromatography)跟踪反应全过程。研究了薄层层析分离的有效展开剂组成及烷基化剂用量、相转移催化剂用量、反应时间对反应的影响,探索了1,2-二甲基吲哚较佳的合成条件。

With the action of phase transfer catalyst(PTC),2-methylindole was N-alky-lated.The effects of different PTC,reacting time,temperature,the concentration of potassium hydroxide and the bromoethane amout on the reaction were studied.The selection of N,C-alkylation was explained theoretically. The relationship of concentration and structures of the catalyst to the reacting rate have been studied quantitatively.

考察了不同相转移催化剂、反应时间、反应温度、氢氧化钾浓度、溴乙烷用量诸因素对2-甲基吲哚进行N-烷基化反应的影响。研究了催化剂浓度和结构与该反应速度的定量关系。

Abstract The phase transfer catalytic synthetic method of 1-buty1-2-methylindole was report-ed in this paper. The optimal experiments of the temperature and the reaction time as well as the amoumts of the catalyst were carried by orthogonal test . The full reaction was followedby thin lalyer chromatography and the final products were analysed by CS-930 thin layer automatic scanner.
