| titleOfInvention | Method for producing 2-aminothiophenols |
| abstract | (57) [Summary] (Correction) [Structure] When 2-aminobenzothiazoles of the formula (1) are hydrolyzed with alkali, a hydrolysis reaction is carried out in the presence of ethylene glycol to obtain the formula (2). 2. A method for producing 2-aminothiophenols. (R is hydrogen, halogen, a nitro group, a methyl group.) [Effect] When 2-aminobenzothiazoles are hydrolyzed with alkali, addition of ethylene glycol does not complete the reaction and unreacted substances remain. Residual or high temperature reaction, Impurity by-products are seen because the reaction time must be lengthened. By adding ethylene glycol, the reaction can be terminated under relatively mild conditions, and the desired reaction product can be obtained in high purity and high yield. |
