With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.39989-39-4,7-Methoxyisoquinoline,as a common compound, the synthetic route is as follows.
Preparation 5 1-Amino-7-methoxyisoquinoline A solution of 8.0 g of 7-methoxyisoquinoline in 45 ml of N,N-dimethylaniline was warmed at 60 C., and then 5.9 g of sodium amide was added. The reaction mixture was heated at 130 C. over a period of 2 hours, and stirred for further 1 hour under the same conditions. After being cooled, the reaction mixture was poured into ice water and extracted with chloroform. The extract was washed with water, and dried over anhydrous magnesium sulfate. The drying agent was removed by filtration, and the solvent was removed under reduced pressure. The residue was purified by column chromatography on silica gel and recrystallized from benzene to give 5.7 g of the title compound as colorless flakes. m.p.: 137.5-138.0 C.; IR(KBr): 3440, 3340, 3150, 3080, 2980, 2850, 1652, 1605, 1569, 1516, 1455, 1428, 1385, 1350, 1298, 1241, 1209, 1190, 1136, 1085, 1032, 915, 890, 853, 830; NMR(CDCL): 7.84(1H,d,J=6.0 Hz), 7.59(1H,d,J=9.0 Hz), 7.20(1H,dd,J=2.0 Hz,9.0 Hz), 7.07(1H,d,J=2.0 Hz), 6.95(1H,d,J=6.0 Hz), 5.33(2H,brs), 3.82(3H,s), 39989-39-4
39989-39-4 7-Methoxyisoquinoline 594375, aisoquinoline compound, is more and more widely used in various fields.
