7-Chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic Acid, cas is 100361-18-0, it is a common heterocyclic compound, the naphthyridine compound, its synthesis route is as follows.
7-F4- (2-HVDROXVETHYLIDENE) PIPERIDIN-1-YLL-1-CVCLOPROPVL-6-FLUORO-4-OXO-1, 4- DIHVDRONAPHTHYRIDINE-3-CARBOXVIIC acid (163) A solution of amine 103 (256 mg, 1.06 MMOL) and triethylamine (0.5 mL, 3.55 MMOL) in ACETONITRILE (4 mL) was treated with 7-CHLORO-1-CYCLOPROPYL-6-FLUORO-4-OXO-1, 4-dihydro-naphthyridine-3- carboxylic acid (200 mg, 0.71 MMOL) under nitrogen and the reaction mixture was allowed to stir for 16 h. The resulting mixture was concentrated in vacuo, and the residue was washed with water (3 x 10 mL) and allowed to dry overnight to afford the title compound 163 (105 mg, 40%). MS 374 (M+H).
With the rapid development of chemical substances, we look forward to future research findings about 100361-18-0
