302964-08-5, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 302964-08-5, name is 2-((6-Chloro-2-methylpyrimidin-4-yl)amino)-N-(2-chloro-6-methylphenyl)thiazole-5-carboxamide. A new synthetic method of this compound is introduced below.
Example 14; Procedure for the Preparation of Dasatinib Form IA mixture of compound 1 (394.3 mg, 1 mmol), N-(2-hydroxyethyl)piperazine (260.4 mg, 2 mmol) and N-ethyldiisopropylamine (0.35 ml, 2 mmol) in pyridine (2 ml) was stirred at 100 C. for 2.5 h. Methyl isobutyl ketone (7 ml) was added to the stirred solution at the same temperature. The suspension was slowly cooled to room temperature. After 1 h the product was filtered off washed with methyl isobutyl ketone (2¡Á) and dried on the filter. Yield: 660 mg.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,302964-08-5, 2-((6-Chloro-2-methylpyrimidin-4-yl)amino)-N-(2-chloro-6-methylphenyl)thiazole-5-carboxamide, and friends who are interested can also refer to it.
