In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Didehydrohetarenes. XXV. Amination of alkyl substituted halopyridines with potassium amide in liquid ammonia, published in 1972, which mentions a compound: 39919-70-5, mainly applied to hetarene didehydro; amination alkylhalopyridine; pyridine alkylhalo amination, Electric Literature of C9H14N2.
The action of KNH2 in liquid NH3 on Me substituted 3- and 4-bromo(or chloro)pyridines, of 5-bromo-2-tert-butylpyridine and of 3-bromo(or chloro) and 4-bromo(or chloro)-2,6-dimethylpyridine was studied. The results of the reactions indicate the occurrence of derivatives of 3,4-didehydropyridine as intermediates. An interpretation is given of the influence of the substituent and the hetero atom on the course of the aminations.
In addition to the literature in the link below, there is a lot of literature about this compound(6-(tert-Butyl)pyridin-3-amine)Electric Literature of C9H14N2, illustrating the importance and wide applicability of this compound(39919-70-5).
