The yield was increased through adding tetrabutyl ammonium bromide as the phase transfer catalyst, and using excessive diisopropyl phosphite to compensate its hydrolyzation.
Sulfadiazine-polylactide, a tumor targeting drug carrier, was successfully synthesized by the phase transfer catalysis(PTC)with tetrabutyl ammonium chloride hydroxide as catalyst.
