| Use | 2-aminobenzothiazole-6-carboxylic acid is a heterocyclic organic compound and can be used as an organic intermediate. 2-aminobenzothiazole is a kind of heterocyclic compounds with a variety of biological activities. For example, riluzole, which is clinically used in the treatment of amyotrophic lateral sclerosis, belongs to 2-aminobenzothiazole compounds; with anti-Virus, intestinal worm and immunosuppressive activity; N-acyl substituted 2-aminobenzothiazole can inhibit HIV Virus; N-aryl substituted 2-aminobenzothiazole has strong anticancer activity. 2-amino benzothiazole is also widely used in antibacterial, antiviral, anti-inflammatory; Treatment of Parkinson's disease, diabetes and other drug research and development. Therefore, 2-aminobenzothiazole plays a very important role in pharmaceutical chemistry. |
| preparation | step 1, 4-amino-3-thiocyanobenzonitrile (3) Take (2)(10.0g,0.08mol), ammonium thiocyanate (13.0g,0.17mol) and 12.8 ml glacial acetic acid were added to a 250ml three-necked flask, and bromine (0.08g, mol) was slowly added dropwise at room temperature. Acetic acid solution 25ml, about 15min. After completion of the reaction, the reaction was stirred for 3H. After completion of the reaction, 11.5 ml of water was added to precipitate a large amount of orange-yellow solid, which was allowed to stand overnight, 91.3%),mp168~170. Step 2, 2-aminobenzothiazole-6-carboxylic acid (4) take (3)(13.0g,0.07mol), ml of water, 60ml of concentrated hydrochloric acid into a ML three-necked flask, the reaction was refluxed and stirred at about 100 ° C. For 10H. When the reaction was complete, the reaction was allowed to stand, and the precipitated solid was collected by filtration, washed with a small amount of water, and dried to obtain an orange-yellow solid product. |
