96568-07-9, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Ethyl 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate, cas is 96568-07-9,the naphthyridine compound, it is a common compound, a new synthetic route is introduced below.
Example 109 7-(4-chloro-2-isoindolinyl)-1-cyclopropyl-6-flurro-1,4- dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid STR325 310 mg of 1-cyclopropyl-6-fluoro-7-chloro-1,4-dihydro-4- oxo-1,8-naphthyridine-3-carboxylic acid ethyl ester, 660 mg of 4-chloroisoindoline, 0.42 ml of triethylamine, and 5 ml of anhydrous chloroform were processed in the same manner as in Example 107 to produce 75 mg of 7-(4-chloro-2- isoindolinyl)-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8- naphthyridine-3-carboxylic acid. Melting point: above 300 C. 1 H-NMR (DMSO-d6) delta: 8.68 (1H, s, C2 –H), 8.06 (1H, d, C5 –H), 7.45-7.55 (3H, m, ARM-H), 5.3 (4H, br, s, 2 x–CH2 N–), 3.83 (1H. m, STR326 1.10-1.40 (4H, m, STR327
The chemical industry reduces the impact on the environment during synthesis,96568-07-9,Ethyl 7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carboxylate,I believe this compound will play a more active role in future production and life.
