WebMar 13, 2024 · A facile, green, synthetic protocol of several substituted N-(pyridin-2-yl)imidates from nitrostyrenes and 2-aminopyridines via the corresponding N-(pyridin-2 … Because of the electronegative nitrogen in the pyridine ring, pyridine enters less readily into electrophilic aromatic substitution reactions than benzene derivatives. Instead, in terms of its reactivity, pyridine resembles nitrobenzene. Correspondingly pyridine is more prone to nucleophilic substitution, as evidenced by the ease of metalation by strong organometallic bases. The react…

WebN-Ethyl-3-aminopyridine 63. To 3-aminopyridine and acetonitrile (5 eqiv.) in methanol was added the catalyst 10% palladium on carbon (30 wt %) and reacted with hydrogen at an ambient temperature and pressure for 58 h. The reaction mixture was filtered and the solution was evaporated to give N-ethyl-3-aminopyridine in 89% yield (Eqn 4.48).
