2289-75-0, 4,5-Dimethylthiazol-2-amine is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 1N-(4,5-dimethylthiazol-2-yl)-2-[5-(6,7-dimethoxyquinazolin-4-yloxy)pyridin-2- yl]acetamideTriethylamine (0.245 ml) and 2-(7-azabenzotriazol-l-yl)-l,l,3,3-tetramethyluronium hexafluoropliosphate(V) (0.236 g) were added in turn to a stirred mixture of2-[5-(6,7-dimethoxyquinazolin-4-yloxy)pyridin-2-yl]acetic acid (0.2 g), 2-amino- 4,5-dimethylthiazole (0.083 g) and DMF (2 ml) and the resultant mixture was stirred at ambient temperature for 40 minutes. A mixture of a saturated aqueous sodium bicarbonate solution (5 ml) and a saturated aqueous sodium carbonate solution (5 ml) was added and the resultant mixture was stirred at ambient temperature for 1 hour. The precipitate was isolated and triturated under diethyl ether. The resultant solid was dried under vacuum at 400C for 16 hours. There was thus obtained the title compound as a solid (0.185 g); 1H NMR: (DMSOd6) 2.1 (s, 3H), 2.2 (s, 3H), 4.0 (m, 8H), 7.4 (s, IH), 7.5 (d, IH), 7.6 (s, IH), 7.8 (m, IH), 8.5 (m, IH), 8.55 (s, IH): Mass Spectrum: M-H’ 450., 2289-75-0
The synthetic route of 2289-75-0 has been constantly updated, and we look forward to future research findings.
