Abstract
A variety of N-vinyl and N-aryl amides were converted in one step into the corresponding pyrimidine and quinazoline derivatives, respectively. Amide activation with trifluoromethanesulfonic anhydride in the presence of 2-chloropyridine followed by nitrile addition to the activated amide derivative and annulation provides the desired azaheterocycles.
Key words
amide - nitrile - pyrimidine - quinazoline - annulation
