3.2.3 Preparation of [(4-cyanophenyl)amino]acetic acid (V). Molecular formula: C9H8N2O2. molecular weight: 176.17. Raw materials: 90g (0.75mol) of bromoacetic acid (F), 211.7g (1.5mol) of p-aminobenzonitrile (G), 35g (0.42mol) of sodium bicarbonate. Procedure: bromoacetic acid (F) and p-aminobenzonitrile (G) were mixed in 1250 ml of water to form a suspension. The suspension was placed in a bath heated to 100-110°C for 3 hours. Upon completion of the reaction, the reaction vessel was removed from the bath and cooled to room temperature, followed by further cooling in a refrigerator. The precipitate was separated by diafiltration and dried in a vacuum desiccator at 100 °C. Yield of crude product: 122 g (92.8% yield), HPLC purity: 97%. Purification step: the crude product was converted to sodium salt and re-acidified using aqueous sodium bicarbonate to release the free acid by dilute hydrochloric acid (1:1). After filtration, the product was washed with water and dried in a vacuum desiccator at 105°C. The product was then purified to a sodium salt using aqueous sodium bicarbonate. Yield of purified product: 115 g (88% yield), HPLC purity: 99.1%, water content: 0.13%, sulfated ash: 1.8%. | [References]
