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. 823-89-2, name is 5-Bromo-2-hydrazinopyrimidine. A new synthetic method of this compound is introduced below., SDS of cas: 823-89-2
5-Bromo-2-hydrazino-pyrimidine (1.02 g, 5.43 mmol) and 6-quinoline acetic acid (1.02 g, 5.43 mmol) were dissolved in dichloromethane (78 mL) and stirred at room temperature for 12 hours. The desired product was insoluble in dichloromethane and precipitated upon formation. The precipitate was filtered off and taken onto subsequent reactions as crude product, quinolin-6-yl-acetic acid N’-(5-bromo-pyrimidin-2-yl)-hydrazide (theoretical yield 1.94 g).
