Abstract
A reactive intermediate 1,2-dihydropyridine derivative 2 has been prepared and isolated from the reaction of pyridine with <TEX>$^tBuLi$</TEX> and trimethylchlorosilane in nonpolar condition at low temperature 2 has characterized by <TEX>$^1H-NMR$</TEX> fine structure analysis with SPINX3. The mechanistic information of formation of 2 was obtained from synthesized 2,5-disubstituted pyridine derivatives 3 and 4.
