실험 절차

이 페이지에서참가 물질실험 절차후처리출처 및 근거반응 노트

4-Chloro-3-nitrobenzoic acid (5.0 g) is suspended in xylene (50 ml), and thereto are added triethylamine (2.5 g) and pyrrolidine (2.0 g), and the mixture is refluxed for 2 hours. To the reaction mixture is added 10% aqueous citric acid solution, and the precipitated crystals are separated by filtration, washed with water and dried to give 3-nitro-4-(1-pyrrolidinyl)benzoic acid (5.6 g).
