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.

(Chemical Equation Presented) A simple, selective, rapid, and efficient procedure for the synthesis of secondary amines from the reductive alkylation of either aliphatic or aromatic nitro compounds and the corresponding amines is reported. Ammonium formate is used as the hydrogen source and Pd/C as the hydrogen transfer catalyst. The reaction is carried out at room temperature. The rate differences for the preferential formation of secondary over tertiary products are due to both steric and electronic factors.
