In this paper, 4-Chlorobenzene-1-carboximidamide Hydrochloride as Reactants,using two different methods of synthesis to optimize the selection of routes and enhance the product yield.The method of Acyl-dimethyl ethyl acetate is can get Product Directly,but Yield is only about 20%,The second reaction route, Through a multi-step reaction,but is easy to operate, and the total yield can be achieved 73%.
