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.

对合成路线中的Friedel-Crafts酰基化反应进行了研究，运用正交实验设计确定了最佳工艺条件：当乙酰苯胺用量为0.1mol时，AlCl_3用量为0.26mol、丙酰氯用量为0.12mol、溶剂用量为200ml、反应时间为5h，产率可达到57.3％；对于固体超强酸催化剂进行了初步研究，合成了四种催化剂，其中负载AlCl_3强酸性树脂对于乙酰苯胺的Friedel-Crafts酰基化具有一定的催化活性。
