4-Nitrophenyl butyrate can be synthesized by reacting p-nitrophenol with butyric anhydride in the presence of a catalyst, such as pyridine. The reaction produces p-nitrophenyl butyrate and acetic acid. The product can be purified by recrystallization or thin-layer chromatography. The purity of the ...
Racemic isocitric acid was first prepared by Fittig and Miller in 1889 by the condensation of chloral with sodium succinate in the presence of acetic anhydride and by the subsequent hydrolysis of the resulting trichloromethylparaconic acid to isocitric acid; this is isolated as the lactone. Formati...
