10601-80-6, name is Ethyl 3,3-diethoxypropionate, belongs to esters-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. HPLC of Formula: C9H18O4
4-Chloro-2-nitrobenzaldehyde (3.71 g, 0.02 mol) was dissolved in ethanol (40 ml).Further adding stannous chloride (18.04g, 0.08mol) and ethyl 3,3-diethoxypropionate (9.5g, 0.05mol), and reacting at 90 C for 4 hours, the reaction of the raw materials of the plate is completed; After the solvent was added, ethyl acetate was dissolved, and neutralized to a weak basic with saturated sodium carbonate; filtered, the organic layer was separated, and the aqueous layer was extracted with ethyl acetate, and then the organic layer was combined, and then evaporated to dryness. Ethyl acetate = 10:1, then petroleum ether: ethyl acetate = 5:1) After washing, ethyl 7-chloro-3-quinolinecarboxylate (3.478 g, 74%).
The synthetic route of 10601-80-6 has been constantly updated, and we look forward to future research findings.
