Adding a certain compound to certain chemical reactions, such as: 1202759-91-8, N4-(3-Aminophenyl)-5-fluoro-N2-(4-(2-methoxyethoxy)phenyl)pyrimidine-2,4-diamine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, category: pyrimidines, blongs to pyrimidines compound. category: pyrimidines
In a 50 mL 3-neck RBF equipped with a magnetic stirrer, calcium chloride guard tube and thermo pocket was charged N4-(3-aminophenyl)-5-fluoro-N2-(4-(2-methoxyethoxyl)phenyl)pyrimidine-2,4-diamine (0.40 g) in dry DCM (10 mL) and was cooled to -30 C. An acryloyl chloride solution in DCM (0.107 g in 5.0 mL DCM) was added slowly and the reaction mixture was stirred at -30 C. for approx. 40 minutes. The reaction was monitored on TLC using chloroform:methanol (9.6:0.4) as mobile phase. The reaction mixture was poured into water (100 mL) and basified using sodium bicarbonate. The reaction mixture was extracted with MDC (2*25 mL) and the combined organic layer was washed with 50 mL brine solution. The organic layer was dried over sodium sulfate and concentrated completely under reduce pressure at 40 C. Obtained solid was purified by triturating with diethyl ether (2*mL) and dried under vacuum to give 0.28 g N-(3-((5-fluoro-2-((4-(2-methoxyethoxyl)phenyl)amino)pyrimidin-4-yl)amino)phenyl)acrylamide.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1202759-91-8, N4-(3-Aminophenyl)-5-fluoro-N2-(4-(2-methoxyethoxy)phenyl)pyrimidine-2,4-diamine, and friends who are interested can also refer to it.
