Abstract: | In the literature, there has appeared a communication [1] on the synthesis of 6-nitro-2, 3-dihydroquinolin-4(1H)-one (I) with mp 125–126C (2,4-dinitrophenylhydrazone, mp 269–270C) by the reaction of p-nitroaniline with acrylic acid. Quinolinone I with mp 232–234C (2,4-dinitrophenylhydrazone, mp 327–329C) was obtained by us by decarboxycyclization of N-(2-carboxy-4-nitrophenyl)--alanine in acetic anhydride in the presence of potassium acetate [2].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1390–1392, October, 1979. |
