Reference of 717843-51-1 ,Some common heterocyclic compound, 717843-51-1, molecular formula is C7H8BrNO, 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.

(3) Synthesis of 3-bromo-5-chloro-2-methoxy-4-methylpyridine 3-bromo-2-methoxy-4-methylpyridine (100 mg) was added to DMF (575 muL). NCS (72.5 mg) was added to the solution, and the mixture was stirred at 80 C. for three hours. The reaction mixture was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate/n-heptane, 5% to 30%) to give the title compound (100 mg). 1H-NMR (400 MHz, CDCl3) delta (ppm): 2.51 (s, 3H), 3.98 (s, 3H), 8.02 (s, 1H).

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,717843-51-1, its application will become more common.
