Abstract:The target o-hydroxyacetophenone derivative was synthesized from 2,4-dimethoxyaniline via N-acetyl protection and Friedel-Crafts reaction. The Friedel-crafts reaction was optimized to obtain the optimum reaction conditions with the yield of 90%. The target compound was characterized by 1H NMR, 13C NMR, IR and MS methods. In addition, a presumed reaction mechanism of the Friedel-crafts reaction was provided and the main by-products were discussed, which provide a theoretical guidance for the synthesis of the title compound. |
Key words:o-hydroxyacetophenone; Friedel-crafts; synthesis |
