Application of 702-24-9, 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. 702-24-9, name is 4-Methoxy-N-methylbenzylamine belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
3-(5-amino-4-fluoro-2-methylphenyl)-7-chloro-1-methyl-1,6-naphthyridin-2(1H)-one (1.36 g, 4.28 mmol, 1.00 eq), 4-methoxy-N-methylbenzylamine (0.971 g, 6.42 mmol, 1.50 eq) and DBU (0.960 mL, 6.42 mmol, 1.50 eq) were combined in NMP (20 mL) and heated at 180¡ã C. under Ar overnight. The mixture was cooled to RT and poured onto H2O (200 mL). The resulting solids were collected by filtration, rinsed very well with H2O, dried on the filter to dampness and then dissolved in EtOAc. The solution was dried (MgSO4), filtered and evaporated to afford 7-((4-methoxybenzyl)(methyl)amino)-3-(5-amino-4-fluoro-2-methylphenyl)-1-methyl-1,6-naphthyridin-2(1H)-one (1.86 g, 100percent yield) as a brittle brown foam which was used as is in the next reaction. 1H NMR (400 MHz, DMSO-d6): delta 8.45 (s, 1H), 7.63 (s, 1H), 7.16 (d, J=8.8 Hz, 2H), 6.85 (d, J=8.8 Hz, 2H), 6.86-6.82 (m, 1H), 6.57 (d, J=9.6 Hz, 1H), 6.29 (s, 1H), 4.88 (br s, 2H), 4.85 (s, 2H), 3.69 (s, 3H), 3.52 (s, 3H), 3.07 (s, 3H), 1.94 (s, 3H); MS (ESI) m/z: 433.3 [M+H]+.
The synthetic route of 4-Methoxy-N-methylbenzylamine has been constantly updated, and we look forward to future research findings.
