Synthesis and Optical Properties of 2-Alkylamino-4-amino-6-arylpyridine-3,5-dicarbonitriles

Simple and Efficient Synthesis of Highly Functional 2-Oxonicotino­nitriles from 2-Chloronicotinonitriles

“…For secondary amines, a side reaction of halogen substitution for the corresponding amine was observed. 45,46 Among the butoxides, potassium tert-butoxide was found to give the best results. It was found that the optimal temperature for the best yield is 25-35 °C.…”
