With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.118452-02-1,2-Aminothiazole-4-carboxamide,as a common compound, the synthetic route is as follows.
4. g (28 mmol) 2-Aminothiazol-4-carboxamide was dissolved in 40 ml glacial acetic acid, to which added 2.8 ml (29.6 mmol) acetic anhydride, followed by reacting under reflux for 2 hr, and naturally cooling down to precipitate a large quantity of solids, which were filtered, washed and dried to obtain 4.7 g 2-acetylaminothiazol-4-carboxamide (yield 92%) with mp>250 C., 118452-02-1
118452-02-1 2-Aminothiazole-4-carboxamide 257149, athiazole compound, is more and more widely used in various fields.
