Abstract:2-Chloro-6-methylthio toluene(2) was synthesized from 3-chloro-2-methylaniline(3) as raw material through diazotization and substitution reaction, with the yield 92.07%. Then 2-chloro-3-methyl-4-methylthioacetophenone(1) was synthesized from compound 2 through Friedel-Crafts acylation, with the yield 90.58%. Both compound 2 and compound 1 were confirmed by 1H NMR. The routes showed the advantages of low waste and high yield. |
Key words:Terfuryltrione; 2-chloro-6-methylthio toluene; 2-chloro-3-methyl-4-methylthioacetophenone |
