What is 3-Aminopyridine?
Part I: Introduction
With the development of science and technology and the progress of society, machinery, medicine, cosmetics, electronics, industry, etc. are all penetrating people’s daily lives. One of these products is 3-aminopyridine, which has developed particularly rapidly.
The official answer: 3-Aminopyridine is white to light yellow needle-like crystals. Melting point 64.5 °C, boiling point 252 °C, 131-132 °C (1.60 kPa). Soluble in water, ethanol, benzene, and ether, insoluble in petroleum ether. It has moisture absorption.
How is 3-aminopyridine synthesized?
Part II: In-depth development
Manufactured from nicotinamide. (1) from 3-bromopyridine, reacted with concentrated ammonia under heating in the presence of copper sulfate; (2) from 3-nitropyridine, hydrolyzed under mild conditions to produce nicotinamide, using the Hofman (Hofman) degradation reaction; (3) from formaldehyde, acetaldehyde, and ammonia to produce 3-methylpyridine, then cyanidated in the presence of ammonia to produce 3-nitropyridine, hydrolyzed to produce nicotinamide, which is obtained by degradation.
