Some common heterocyclic compound, 2393-23-9, name is 4-Methoxybenzylamine, molecular formula is C8H11NO, 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. Recommanded Product: 4-Methoxybenzylamine
1.1. Synthesis of bis-(4-methoxy-benzyl)-amine (Int. 1) p-Anisaldehyde (411 mmol), 4-methoxybenzylamine (411 mmol) and toluene (500 mL) were combined in a round bottomed flask fitted with a condenser and a Dean-Stark trap. The reaction was refluxed for 1 h during which water was removed from the reaction mixture. The reaction was cooled and concentrated. The residue was dissolved in MeOH (120 mL). The mixture was cooled to 5 C. and NaBH4 (205 mmol) was added in portions over 45 min. The reaction was slowly heated to reflux. After 2 h at reflux, the reaction was cooled to room temperature and concentrated. The residue was dissolved in EtOAc. The organic layer was washed (3*H2O and brine), dried (Na2SO4) and concentrated to yield the desired product.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2393-23-9, its application will become more common.
