Name is 7-Chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic Acid, as a common heterocyclic compound, it belongs to naphthyridine compound, and cas is 100361-18-0, its synthesis route is as follows.
A solution of amine 135 (0.48 MMOL) and triethylamine (0.28 mL, 2.0 MMOL) in acetonitrile (7 mL) was treated with 7-CHLORO-1-CYCLOPROPYL-6-FLUORO-4-OXO-1, 4- DIHYDRO- [1, 8] naphthyridine-3-carboxylic acid (113 mg, 0.40 MMOL) under nitrogen. After 5 min, the reaction mixture was warmed to reflux temperature and the reaction mixture was allowed to stir for 24h. The resulting mixture was allowed to cool to room temperature, concentrated in vacuo and the residue was diluted with water. The product was collected by filtration, and then washed with water and a small amount of methanol to afford the title compound (178 mg, 87%) as a white solid. MS 511 (M+H).
100361-18-0, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,100361-18-0 ,7-Chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic Acid, other downstream synthetic routes, hurry up and to see
