Application of 17061-62-0, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 17061-62-0, name is Bis(4-methoxybenzyl)amine belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a solution of bis(4-methoxybenzyl)amine 30.1 (900 g, 3.49 mol, 1 eq) in DCM (9 L) was added TEA (634 mL, 4.55 mol, 1.3 eq) followed by dropwise addition of ethanesulfonyl chloride (399 mL, 4.19 mol, 1.2 eq). (The internal temperature was kept between 5-10 C during the addition of the ethanesulfonyl chloride). Once the addition was complete, the cooling bath was removed. After 1.5 h, TLC showed complete loss of starting material. The reaction was quenched by the addition of water (4 L) to the reaction mixture. The layers were separated and the aqueous layer extracted with DCM (2x 2 L). The combined organic layers were washed with brine (2x 1 L), dried over Na2SO4, and concentrated in vacuo. The material thus obtained was adsorbed onto a plug of silica gel and purified by chromatography (silica gel (60-120 mesh) eluting with a gradient of 10-80% EtOAc in hexanes) to provide the title compound 30.0 (1125 g, 3.22 mol, 92%) as white solid. 1H- NMR (400 MHz, CDC13) oe 7.23 (dd,J= 2.08, 6.62 Hz, 4H), 6.90 (dd,J= 2.12, 6.60 Hz, 4H), 4.29 (s, 4H), 3.83 (app s, 6H), 2.92 (q,J= 7.40 Hz, 2H), 1.33 (t,J= 7.40 Hz, 3H). GC-MS (ESI pos. ion) m/z: = 372.2 (M+Na).
The synthetic route of Bis(4-methoxybenzyl)amine has been constantly updated, and we look forward to future research findings.
