introduction | 3-amino -5-bromo -2-methoxypyridine is a light green solid and slightly soluble in water. 3-Amino-5-bromo-2-methoxypyridine is a pyridine derivative with a certain alkalinity. It can be used as a denaturant, dye aid, and synthesis of a series of products (including drugs, Disinfectants, dyes, etc.). |
use | 3-amino -5-bromo -2-methoxypyridine can be used as a pharmaceutical intermediate, a synthetic intermediate for coatings. In the synthetic transformation, it mainly revolves around the bromine atom and amino group on the pyridine ring. The common transformation is to convert the bromine atom into boric acid or borate; the amino group is converted into halogen atom through diazotization. |
synthesis method | combine 5-bromo-2-methoxy-3-nitropyridine (5.0g, 21.55 mmol) and tin chloride (II) dihydrate (24.35g, dissolve the mixture 107.75 mmol) into ethyl acetate (0.2 L), stir the mixture at 50°C for 3 hours under nitrogen atmosphere, dilute the mixture with EtOAc (0.8 L), wash the mixture twice with 1 N sodium hydroxide (1.2 L) and water, dry the mixture with magnesium sulfate, filter to remove magnesium sulfate solid precipitate, the resulting filtrate was concentrated to obtain 3-amino-5-bromo-2-methoxypyridine.
