A general and versatile synthesis of 2-alkyl-4-aminopyridines
Hedge, Vidyadhar B.,Renga, James M.,Owen, John M.
, p. 1847 - 1850 (2007/10/03)
A versatile two-step synthesis of 2-alkyl-4-aminopyridines from commercially available cis-1-methoxy-1-buten-3-yne is described. Acylation of the yne derivative followed by amination and cyclization in ammonia produced the desired substituted pyridines in high yield.
