Synthesis of 6-Amino-4-aryl-5-(4-arylthiazol-2-yl)-2-ethoxynicotinonitriles
Reactions of 2-(4-arylthiazole-2-yl)acetonitriles with 4-methoxybenzylidenemalononitrile and potassium hydroxide or (2E)-3-aryl-2-(4-arylthiazole-2-yl)acrylonitriles with malonitrile and sodium ethylate in ethanol proceeded to form 6-amino-4-aryl-5-(4-arylthiazole-2-yl)-2-ethoxynicotinonitriles with yields of 32–65%. Treatment of 6-amino-2-ethoxy-4-(4-methoxyphenyl)-5-[4-(4-methoxyphenyl)thiazole-2-yl]nicotinonitrile with an excess of molecular bromine produced 6-amino-5-[5-bromo-4-(4-methoxyphenyl)thiazole-2-yl]-2-ethoxy-4-(4-methoxyphenyl)nicotinonitrile with a yield of 45%.
期刊介绍:
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
