| titleOfInvention | Production of 2-methoxy-6-methylaminopyridine |
| abstract | PURPOSE: To obtain the title compound in high yield, by reacting 2-chloro-6- methylaminopyridine with methanol in the presence of an alkali metal hydroxide, adding a specific amount of water to the reaction product, heating the mixture to completely recover the methanol and subjecting the product to filtration and separation. n CONSTITUTION: The objective compound useful as an intermediate for pharmaceuticals and agricultural chemicals can be produced by (1) reacting 2-chloro-6-methylaminopyridine with methanol in the presence of an alkali metal hydroxide (e.g. sodium hydroxide), (2) adding 1.5W10.0pts.wt. of water to the reaction mixture based on 1pt.wt. of the produced 2-methoxy-6-me thylaminopyridine, (3) slowly raising the temperature of the system preferably from the boiling point of methanol finally to the boiling point of water to com pletely recover the methanol and (4) separating the objective compound by simplified filtration process. The methanol recovered by the above process can be reused as a reaction raw material. n COPYRIGHT: (C)1989,JPO&Japio |
