Synthesis

619-65-8

56-91-7

General procedure for the synthesis of 4-(aminomethyl)benzoic acid from 4-cyanobenzoic acid: 4-cyanobenzoic acid (500 g, 3.4 mol) was suspended in methanol (5 L) with Raney nickel catalyst (100 g) and subjected to catalytic hydrogenation under hydrogen pressure of 10 kg/cm2 for 16 hours. Upon completion of the reaction, the catalyst was removed by filtration followed by distillation under reduced pressure to remove the solvent methanol, resulting in the white solid product 4-(aminomethyl)benzoic acid (430 g, 84% yield).

Questions And Answer

• Description

  4-(Aminomethyl)benzoic acid is a organic compound that can serve as a type 2 antifibrinolytic agent used in the treatment of fibrotic skin disorders, such as Peyronie's disease. It is believed that 4-(Aminomethyl)benzoic acid is effective to increase the oxygen uptake at the tissue level and enhance activity of monoamine oxidase, thus to promote the degradation of serotonin, which in excess, may lead to fibrotic changes. It is also administrated by mouth to treat several skin conditions including vitiligo, pemphigus, dermatomyositis, morphea, lymphoblastoma cutis and scleroderma. It is sometimes used in pill form by patients suffering from irritable bowel syndrome to treat the relevant gastrointestinal symptoms and applied in nutritional epidemiological studies to assess the completeness of 24-hour urine collection for the determination of urinary sodium, potassium, or nitrogen levels. Besides, it can also serve as nutritional supplements to darken gray hair, prevent hair loss, make skin look younger and prevent sunburn and its benefits are claimed for people with fatigue, irritability, depression, weeping eczema, scleroderma, patchy pigment loss in skin, and premature grey hair. ;
