Paragraph 0029-0031, (2017/05/26)
The invention belongs to the field of chemical synthesis, and discloses a method for preparing 3-(dipropyl amino)-4-methoxyl benzenesulfonic acid. The 3-(dipropyl amino)-4-methoxyl benzenesulfonic acid takes 2-anisidine as the raw material and is prepared through two steps of reaction. The invention provides the synthesis method for the 3-(dipropyl amino)-4-methoxyl benzenesulfonic acid for the first time, and offers the synthesis route for preparation of the 3-(dipropyl amino)-4-methoxyl benzenesulfonic acid; and the preparation method is simple, has high yield and low cost, and can be used for large-scale production.
