5-Amino-2-methoxypyridine Chemical Properties,Usage,Production
Chemical Properties
yellow-brown or red to very dark red liquid
Uses
5-Amino-2-methoxypyridine is used as a reagent in the synthesis of a novel series of thienopyrimidines as highly potent and selective PI3K inhibitors. 5-Amino-2-methoxypyridine is also used to synthesize EMPA (E521550); a novel high-affinity selective antagonist for the OX2 receptor.
Definition
ChEBI: 6-Methoxypyridin-3-amine is an aminopyridine.
Application
5-Amino-2-methoxypyridine is widely used in drug synthesis, organic synthesis and materials science due to its unique chemical properties and diverse reaction pathways.
Chemical Reactivity
The amino unit in 5-Amino-2-methoxypyridine structure has significant nucleophilicity. It can undergo condensation reactions with acyl chlorides under alkaline conditions to give the corresponding amide derivatives, and it can also undergo condensation reactions with organic carboxylic acids in the presence of condensing agents.
Synthesis
5446-92-4
6628-77-9
The general procedure for the synthesis of 5-amino-2-methoxypyridine from 5-nitro-2-methoxypyridine was as follows: 67.28 g of 2-methoxy-5-nitropyridine (0.1 mol), 0.50 g of 10% Pd/C were sequentially added to methanol, hydrogen was passed to a pressure of 0.01 MPa, and the reaction was carried out for 62±1.5 hours. Upon completion of the reaction, the reaction solution was cooled to room temperature and filtered to recover the 10% Pd/C catalyst. The filtrate was concentrated under reduced pressure to recover solvent. The residue was extracted twice with 75 g of dichloroethane and the combined extracts were washed once with purified water. Subsequently, the extract was evaporated under reduced pressure to afford a slightly yellow oily liquid 5-amino-2-methoxypyridine 11.69 g. The purity was determined by HPLC to be 97.63% and the yield was 92.03%.
