Some common heterocyclic compound, 929-75-9, name is 1,11-Diamino-3,6,9-trioxaundecane, molecular formula is C8H20N2O3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. 929-75-9
General procedure: A mixture of cinnamic acid (6.30 mmol), EDCI (7.50 mmol), DMAP (0.60 mmol), and anhydrous dichloromethane (20 mL) was stirred to dissolve, then diamino-ether (3 mmol) was added and stirred at room temperature for 12 h. Then, the solid was filtered off, the filtrate was added with H2O (50 mL) and extracted by dichloromethane three times. The combined organic layers were washed with H2O and brine, dried with anhydrous sodium sulfate for 8 h, filtered, and evaporated. The resulting residue was purified by preparative TLC with petroleum ether/ethyl acetate = 2:1-1:1 to give pale white solid or light yellow oil.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 929-75-9, its application will become more common.
