In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 5414-19-7 as follows. Product Details of 5414-19-7
Part F:; To a DMF (9 mL) solution of Part E (1.08 g, 2.71 mmol) was added K2CO3 (1.12 g, 8.16 mmol), 18-crown-6 (0.21 g, 0.80 mmol), and bis (2-bromoethyl) ether (0.37 mL, 2.9 mmol). The slurry was stirred at 60C for 72 hr. Additional bis (2-bromoethyl) ether was added at 24 hr (0.4 mmol) and 48 hr (1.2 mmol). The solvent was stripped in vacuo, and the residue was partitioned between ethyl acetate (50 mL) and water (30 mL). The organic layer was separated, dried over MgS04, and evaporated to an oil. Recrystallization from diethyl ether produced 0. 88 g (69 %) of the desired compound in the form of a white solid. LCMS: itvz = 469.2 (M+H).
According to the analysis of related databases, 5414-19-7, the application of this compound in the production field has become more and more popular.
