Electric Literature of 7477-10-3 ,Some common heterocyclic compound, 7477-10-3, molecular formula is C6H3ClN2O4, 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.
Methyl 6-chloro-5-nitronicotinate was purchased from Sigma Aldrich or synthesized as follows. Toa solution of 6-chloro-5-nitronicotinic acid (Ark Pharm, Inc., 2.5 g, 12.3 mmol) in dry DMF (30mL) were added K2CO3 (2.5 g, 18.5 mmol) and iodomethane (8.76 g, 61.7 mmol). The solution wasstirred at room temperature for 24 h, then poured onto ice, and extracted with EtOAc (100 mL × 3).The organic layer was washed with H2O (100 mL × 2) and brine (100 mL), and dried over MgSO4.The solvent was evaporated under reduced pressure and the residue was purified by flash columnchromatography (EtOAc/n-hexane = 1/2) to afford 10 (2.4 g, 92percent) as a yellow solid.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,7477-10-3, its application will become more common.
