What is 4-Methoxypyridine?

Chemical properties

clear colorless to slightly yellow liquid

The Uses of 4-Methoxypyridine

4-Methoxypyridine, is used as a building block for the synthesis of some biologically active compounds. It is used for the preparation of a new series of benzoylated N-ylides as protein farnesyltransferase inhibitors.

The Uses of 4-Methoxypyridine

4-Methoxypyridine was used as a starting reagent for the stereocontrolled synthesis of (±)-pumiliotoxin C and (±)-lasubine II. It was also used in an efficient construction of dihyropyridin-4-ones, which serves as potential ligands for neuronal nicotinic acetycholine receptors.

General Description

4-Methoxypyridine has been prepared from 4-methoxypyridine-N-oxide, via catalytic hydrogenation. Ortho lithiation of 4-methoxypyridine using mesityllithium as the metalating base has been studied.
