Related Products of 607373-83-1 , The common heterocyclic compound, 607373-83-1, name is 2-Chloro-4-methoxy-5-nitropyridine, molecular formula is C6H5ClN2O3, 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.
To a suspension of 2-chloro-4-methoxy-5-nitropyridine (300 mg, 1.59 mmol), prepared according to a literature procedure (PCT Int. Appl. (2003), WO 2003080610 Al 20031002) in EtOH (3 mL) was added SnCl2.2H20 (1.44g, 6.36 mmol) and the the mixture heated at 90C for lhr. The solvents were evaporated and the residue partitioned between 3M NaOH (50 mL) and DCM (lOOmL). The phases were separated and the organic phase was washed with brine (20 mL), dried (Na2SC>4), the mixture filtered and the filtrate evaporated to dryness to afford the title compound as a yellow oil (174 mg, 69%); m z=158.9, 160.8 (MH)+.
The synthetic route of 607373-83-1 has been constantly updated, and we look forward to future research findings.
