4-Amino-2-ethoxypyridine Chemical Properties,Usage,Production
Uses
4-Amino-2-ethoxypyridine is a pharmaceutical intermediate in the synthesis of other pharmaceutical compounds and is commonly used in research and chemical synthesis processes, but is not directly used as a drug to treat humans or animals.
Synthesis
7598-35-8
89943-12-4
The general procedure for the synthesis of 2-ethoxy-4-aminopyridine from 4-amino-2-bromopyridine is as follows: 1. 2-Bromo-4-aminopyridine (4 g), solid sodium hydroxide (4 g) and ethanol (15 ml) were placed in a reactor and heated at 160°C for 6 hrs followed by cooling to room temperature. 2. Water was added to the reaction mixture and then the solvent was partially evaporated under reduced pressure. 3. The mixture was extracted using ether and the solvent was subsequently evaporated to give a clarified oily product of 2-ethoxy-4-aminopyridine (164 g, 76% yield). 4. The oily product slowly crystallized to form colorless needle-like crystals with a melting point of 88-89 °C. The product was extracted with ether and subsequently evaporated.
