Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 702-24-9, name is 4-Methoxy-N-methylbenzylamine, A new synthetic method of this compound is introduced below., Safety of 4-Methoxy-N-methylbenzylamine
A mixture of 3-(5-amino-2-chlorophenyl)-7-chloro-1-methyl-1,6-naphthyridin-2(1H)-one (5 g, 15.67 mmol), 4-methoxybenzylmethylamine (3.6 g, 23.5 mmol) and DBU(3.7 g, 23.5 mmol) in NMP (80 mL) was heated at 180¡ãC under N2 for 4 h. The reaction wascooled toRT and poured into water (600 mL). The precipitate was collected by filtration anddried in vacuo to give 7-((4-methoxybenzyl)(methyl)amino)-3-(5-amino-2-chlorophenyl)-1-methyl-1,6-naphthyridin-2(1H)-one (6.5 g, 95percent yield). 1H NMR (400 MHz, DMSO-d6): 88.46 (s, 1 H), 7.68 (s, 1 H), 7.16 (d, J = 8.8 Hz, 2 H), 7.06 (d, J = 8.4 Hz, 1 H), 6.85 (d, J = 8.8Hz, 2 H), 6.54-6.51 (m, 2 H), 6.29 (s, 1 H), 5.23 (s, 2 H), 4.85 (s, 2 H), 3.69 (s, 3 H), 3.51 (s,3 H), 3.07 (s, 3 H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
