Abstract

2-Methoxypyridines functionalized in the 3-, 5-, or 6-position and 2,6-dimethoxypyridines functionalized in the 3-position were prepared from the corresponding bromo or iodo analogues by using lithium dibutyl(isopropyl)magnesate(1-) and lithium chloride under noncryogenic conditions. The procedure was optimized in terms of the choice between two magnesates and the presence or absence of lithium chloride in the reaction medium.

Key words

pyridines - magnesium - lithium - organometallic reagents
