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.
Synthesis
N-Methyl-3-pyridinamine is an organic intermediate. It can be used as a raw material to prepare 4-methyl-N-(pyridin-3-yl)benzenesulfonamide, which is then methylated to prepare N,4-dimethyl-N-(pyridin-3-yl)benzenesulfonamide, and then deprotected to obtain N-Methyl-3-pyridinamine.
