As a key step of the synthesis, the Friedel-crafts acylation was researched. And the optimal operation variables were determined through orthogonal experiment: when 0.lmol acetanilide, 0.26mol aluminum chloride, 0.12mol propionyl chloride and 200ml carbon disulfide are introduced, and the reaction time is 5 hour, the yield can be up to 57.3%. The solid super acid catalyst was preliminary studied. Four solid super acid catalysts were prepared to take the place of aluminum chloride, and it was indicated that AlCl3 acidic resin can better catalyze the Friedel-Crafts reaction of acetanilide.
