Related Products of 19346-43-1 , The common heterocyclic compound, 19346-43-1, name is 2-Fluoro-3-nitro-4-picoline, molecular formula is C6H5FN2O2, 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.
A solution of 7-chloro-IH-indazol-5-arnine (100 mg, 0.597 mmol) and 2-fluoro-4-methyl-3-nitropyridine (93 rng, 0597mmol) in DMF (1.5 rnL) was reacted in the microwave at 150 0Q for 2 h. The reaction was diluted with water and EtOAc and extracted with EtOAc. The combined organic layers were dried (Na2SO4), filtered, and concentrated in vaeuo. Purification (FCC, Si02, 0-70-100% EtOAc in hexanes) afforded the title compound (38 rng, 21%). ?H NMR (400 MHz, CDC13) b S. 20 (s, 1Ff), 8.19 (d, J:::: 4.8 Hz, 1H), 8.09 (s, 1H), 783 (d, J 1.7 Hz, 1Ff), 7.56 (d, J == 1.7 Hz, IH), 6.72-6.67(m, iH, 2.60 (s, 3H.
The synthetic route of 19346-43-1 has been constantly updated, and we look forward to future research findings.
