N-Methyl-3-pyridinamine Usage And Synthesis

Application

3-Methylaminopyridine is an organic intermediate that can be prepared from 3-aminopyridine as a raw material. 4-Methyl-N-(pyridin-3-yl)benzenesulfonamide can be prepared first, then methylated to prepare N,4-dimethyl-N-(pyridin-3-yl)benzenesulfonamide, and then deprotected to obtain 3-methylaminopyridine.
