Related Products of 88912-27-0 , The common heterocyclic compound, 88912-27-0, name is 3-Chloroisonicotinic acid, molecular formula is C6H4ClNO2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Reference Production Example 48 A mixture of 0.3 g of 2-amino-4-trifluoromethoxy phenol, 0.29 g of 3-chloroisonicotinic acid, 1.04 g of (benzotriazole-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (hereinafter, referred to as a BOP reagent), 0.24 g of triethylamine and 5 ml of DMF was stirred at room temperature for two hours. Water was added to the reaction mixture, precipitated solid was collected by filtration. The resultant solid was dissolved in ethyl acetate. Then, the organic layer was washed with a saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 0.43 g of 3-chloro-N-[2-hydroxy-5-(trifluoromethoxy)phenyl]isonicotinamide. [Show Image] 1H-NMR (DMSO-d6) delta: 10.37 (br s, 1H), 10.15 (br s, 1H), 8.75-8.73 (m, 1H), 8.64-8.61 (m, 1H), 8.04-8.01 (m, 1H), 7.63-7.60 (m, 1H), 7.07-7.02 (m, 1H), 6.98-6.94 (m, 1H)
The synthetic route of 88912-27-0 has been constantly updated, and we look forward to future research findings.
