100361-18-0, 7-Chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic Acid is a naphthyridine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
100361-18-0, Acetonitrile (100ml), 3-aminomethyl-4-methoxyiminopyrrolidine dimethanesulfonate (12. 5g), 2-hydroxybenzaldehyde (8.6g) and triethylamine (12.2g) were in turn introduced into a reaction vessel at room temperature. After stirring the mixture for about 0. 5h, 7- chloro-1-cyclopropyl-6-fluoro-1, 4-dihydro-4-oxo-1, 8- naphthyridine-3-carboxylic acid (lO. Og) was introduced thereto. The resultant reaction mixture was stirred for about 15h at room temperature, cooled to O~ 5 C, and stirred for about 3h. The title compound in the form of solid was filtered, washed with acetonitrile, and dried to prepare 16.0 g of the title compound (Yield: 91. 8%). ‘H NMR (6, CDC13) : 8. 68 (s, 1H), 8.42 (s, 1H), 8.01 (d, J=12.4Hz, 1H), 7. 30-7. 20 (m, 3H), 6. 90-6. 82 (m, 2H), 4. 68-4. 53 (m, 2H), 4. 32-4. 24 (m, 1H), 4.06 (dd, J1=11. 9Hz, J2=5. 5Hz, 1H), 4. 02-3. 85 (m, 3H), 3.95 (s, 3H), 3.60 (m, 1H), 3.40 (m, 1H), 1. 29-1. 21 (m, 2H), 1. 07-1. 00 (m, 2H) Mass (FAB): 494 (M+H)
The synthetic route of 100361-18-0 has been constantly updated, and we look forward to future research findings.
