| titleOfInvention | Method for preparing 2-cyano-6-methoxybenzthiazole |
| abstract | FIELD: organic chemistry, chemical technology. n SUBSTANCE: invention relates to the improved method for synthesis of 2-cyano-6-methoxybenthiazole that is a key intermediate compound used in synthesis of luminescent biological systems, in particular, lupiferin. Method involves cyaniding reaction of 2-chloro-6-methoxybenzthiazole wherein acetonecyanohydrine is used as a cyaniding agent that is treated with alkaline metal alcoholate alcoholic solution, benzene is added and azeotropic mixture alcohol-benzene is distilled off followed by addition of dimethylsulfoxide and 2-chloro-6-methoxybenzthiazole. Method allows avoiding contact of workers with highly toxic cyanides and to obtain 2-cyano-6-methoxybenzthiazole with higher yield 50-50.8% as compared with the prototype (40%). n EFFECT: improved method of synthesis. n 3 ex |
