Synthesis of dialkylaminocarbonyl N-chloro- carbonyl-N-phenyl-4-aminobenzo-(-pyrone derivatives

The title compounds were prepared by condensation of N-chlorocarbonyl-N-phenyl-4-aminobenzo-(-pyrone with diethylamine dibutylamine and isopropylamine. The starting compound used for condensation with amines was obtained by a reaction of N-phenyl-4-aminobenzo-(-pyrone with oxalyl chloride.
