Paragraph 0113; 0119; 0120; 0121, (2016/11/17)
The invention provides a synthetic method of 2-amino-4-(ethylsulfonyl) phenol. The method comprises the following steps that firstly, 4-ethylsulfonyl-2-nitro-chlorobenzene and alkali are subjected to a reaction in a solvent to obtain 4-(ethylsulfonyl)-2-nitro-phenol; then, the 4-(ethylsulfonyl)-2-nitro-phenol obtained in the last step is reduced to obtain 2-amino-4-(ethylsulfonyl) phenol. The novel synthesis route is designed, no high temperature or high pressure is needed in the reaction process, reaction conditions are mild, and the reaction yield and product purity are high, so that the production cost of the product is lowered, the product quality is improved, the preparation technology is more reasonable, and large batch industrial production is facilitated.
