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. 41965-95-1, name is 3-Chloro-4-methoxybenzylamine Hydrochloride, A new synthetic method of this compound is introduced below., Recommanded Product: 41965-95-1
2-acetyl-10-[(3-chloro-4-methoxybenzyl)amino]-1,2,3,4-tetrahydrobenzo[b][1,6]naphthyridine-8-carbonitrile, H A mixture of 26 (0.14 mmol), 3-chloro-4-methoxybenzyl amine hydrochloride (0.70 mmol), TEA (0.70 mmol) and NaI (0.007 mmol) in NMP (2 mL) was heated to 130 C. and stirred overnight. The mixture was diluted with CH2Cl2 (10 mL) and washed with H2O (2*10 mL) and brine (10 mL). The organic layers were dried over Na2SO4, filtered and evaporated under reduced pressure. Flash Chromatography (AcOEt:MeOH 9:1) gave the desired product (20% yield). MS ESI (m/z) 421 (M+H)+; 1H NMR (300 MHz, CDCl3) delta 8.34 (s, 1H), 7.96 (d, 1H, J=8.7 Hz), 7.73 (dd, 1H, J1=1.5, J2=9.0 Hz), 7.31 (d, 1H, J=2.1 Hz), 7.20 (dd, 1H, J1=2.1, J2=8.4 Hz), 6.93 (d, 1H, J=8.1 Hz), 4.70 (s, 2H), 4.64 (d, 2H, J=6.0 Hz), 4.42 (s, 1H), 3.91 (s, 3H), 3.82 (t, 2H, J=6.0 Hz), 3.20 (t, 2H, J=6.0 Hz), 2.21 (s, 3H).
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.
