چکیده
|
Two new 1,2,4-triazines 5a and 5b were obtained in a 92 : 8 ratio by condensation of the new amino keto-amide 4 with hydrated hydrazine in the presence of acetic acid. the previously unreported amino keto-amide 4 was obtained from p-chloroacetophenone (1) in three steps. both of the triazines were characterized by their spectral data.
