Application of 2393-23-9, These common heterocyclic compound, 2393-23-9, name is 4-Methoxybenzylamine, its 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.
A mixture of l-[4-(methyloxy)phenyl]methanamine (40 g) and 4- (methyloxy)benzaldehyde (40.5 g) in methanol (220 mL) was heated to reflux for 3 hours. After cooling to 0 C, NaBH4 (14.34 g) was added portionwise within 30 min and the resulting mixture was stirred at room temperature overnight. Solvent was removed under reduced pressure and the residue was partitioned between EtOAc and water. The aqueous phase was extracted with EtOAc for 3 times. The combined organic layers were washed with water and brine, then dried over anhydrous Na2SC>4. After filtration, solvent was removed in vacuo to afford bis {[4-(methyloxy)phenyl]methyl} amine (75.9 g) as a colorless oil. MS(ES+) m/z 258 (MH+).
Statistics shows that 4-Methoxybenzylamine is playing an increasingly important role. we look forward to future research findings about 2393-23-9.
