| Abstract: | Heating 4-nitronaphthalic anhydride in an excess of 3(5)-methylpyrazole gives only 4-(3-methylpyrazolyl-1)naphthalic anhydride, which is converted by butylamine into the known N-butylimide of 4-(3-methylpyrazolyl-1)naphthalic acid.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, p. 194, February, 1992. |
