With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.15936-10-4,2-Chloro-1,8-naphthyridine,as a common compound, the synthetic route is as follows.,15936-10-4
Example 82; 5-Methvl-6- (1, 8-naphthyridin-2-yl)-N [4-trifluoromethvl phenvl] pyrimidin-4-amine; To a mixture of Description 95 (200 mg, 0.7 mmol), Description 92 (115 mg, 0.7 mmol) and Pd (PPh3) 4 (80 mg, 0.07 mmol) in anhydrous 1, 4-dioxane (4 ml) was added hexamethylditin (0. 145 ml, 0.7 mmol). The mixture was heated at 190C for 15 min in a microwave reactor (Personal Chemistry-Smith synthesizer). The cooled reaction mixture was loaded directly onto a silica gel chromatography column and eluted with 2% MeOH + 0. 5% NH40H in DCM. The product was further purified by mass directed HPLC to give the title compound as a white solid (50 mg, 18%). 1H NMR (500 MHz, CDCl3) 2.70 (3 H, s), 6.94 (1 H, s), 7. 58 (1 H, dd, J8.1 and 4.2), 7.64 (2 H, d, J8.6), 7.84 (2 H, d, J8.6), 8. 25 (1 H, d, J8. 5), 8.29 (1 H, dd, J8. 1 and 1. 9), 8.38 (1 H, d, J 8. 4), 8. 81 (1 H, s), 9.20 (1 H, dd, J4.2 and 1.9) ; mlz (ES+) 382 (M+H+).
15936-10-4 2-Chloro-1,8-naphthyridine 5152838, anaphthyridine compound, is more and more widely used in various fields.
