2-Arylamino-3-Cyano-5,6,7,8-tetrahydroquinolines and 2-substituted 1-aryl-6,7,8,9-tetrahydropyrimido[4,5-b]-quinolin-4-ones derived therefrom

Reaction of 2-chloro-3-cyano-5,6,7,8-tetrahydroquinoline with arylamines gives 2-arylamino-3-cyano-5,6,7,8-tetrahydroquinolines, which on reaction with acetic anhydride or benzoyl chloride are converted into the N-acyl derivatives, and on further treatment with hydrogen chloride in anhydrous ethanol, into 2-substituted 1-aryl-6,7,8,9-tetrahydropyrimido4,5-b]quinolin-4-ones.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 1, pp. 85–87, January, 1988.
