This paper is about the preparation method of ACC. The finely divided barium carbonate-14C is used to react with sodium azide to obtain potassium cyanide-14C. From potassium cyanide-14C
the derivative of p-bromo-benzoic imine of glycine-14C is synthesized. The derivative is dissolved in DMF containing anhydrous K2CO3.The mixture is refluxed with 1.2-dibromo-ethane extracted and depurated under absolute ether. The residure is hydrolyzed by refluxing with 2mol/l HCl. Finally the 1-amino-cylopropane-l-carboxylic acid(ACC) is obtained. The yield of K14CN
14-Gly
14C-ACC are 94.3%
90%
52% respectively. The ACC is purified and both the chemical purity and radioactive purity of ACC are 99%.
